Haunted Halloween Challenge Winners!

The winners of our Haunted Halloween Challenge were certainly scary... scary awesome that is! Here's the designs that shone bright, came out on top, and won some filament!

First, our runners up — each winning 3 rolls of filament in the colors of their choice...

"Ghost Candle" by: Lily Porter

We like this shocked little ghost for its clean design and the fact that it was easy to print a whole squadron with very little support material. We did get one tip from Lily to help potential printers: "In order to fit the candle, size it to 120(%) or larger."

"Starry Pumpkin" by: Travis Fortney

Travis' design utilizes a cool star pattern and inverted our tutorial, putting the hole at the top like a traditional pumpkin. We bet the star shadows and lights that display on the surrounding ground — once this print is lit — is pretty impressive.  

Finally, the grand prize winner... *drumroll* ...

"Spiderweb Pumpkin" by: Jayna Searles

This object is so cool — and the complexity of the spider-web and spider on the pumpkin is such a great touch! Jayna let us know that this object really looks great lit, which is exactly what we were looking for : "This print will be perfect for a table where it glows in a neat pattern." How fun is that?!  

But more important than the cool spider web, Jayna's challenge entry shows a great lesson of the challenges of new designs in 3D printing: try, try again. Just as we espouse in our STEAMtrax education system, the design process is hinged on trial and error — and Jayna re-tried printing her great design after a filament bind during her first print — and got a successful print on try two! Congratulations to Jayna for her grit and perseverance in making such a great design. Jayna and the runners-up will be contacted shortly for their filament preferences and be sent their prizes shortly! Thank you to everyone for participating and keep an eye out for our next challenge centered around the Thanksgiving table!

Haunted Halloween Challenge Tutorial

A 3D Printed Jack O Lantern with an LED candle inside lights up the whole print!

We've just launched the Haunted Halloween Challenge! This challenge is a little different than previous ones — we'd like you to make a design that should be lit up from the inside! It seemed like a great opportunity to help out our students and teachers with a little tutorial.

Due to the fact that excessive heat and finished 3D Prints don't mix too well, we suggest that you use a flameless LED candle to make your prints light up. As evidenced by the adjacent photo, it works really well! You can find inexpensive, flameless LED candles at most major stores, especially during this Halloween season.

To make a hole big enough for a flameless candle in your model, first you'll need to measure the candle you'd like to insert. Our candle, for the sake of the tutorial, was roughly 1.5" (38mm) in diameter and 1.5" (38mm) tall. To ensure enough room inside the print, we decided that making a slightly larger cylinder of 1.75"D (44mm) x 1.75"H (44mm) would work best. We suggest that you also make the hole slightly bigger than your candle to be safe. 

Now you'll need to create the spooky model you'd like to illuminate. That part is entirely up to you and we look forward to seeing your design! For our tutorial, we've started with a basic, not-so-scary pumpkin in the center of the workplane. We first raised the pumpkin to make some space beneath it. Next, we created the cylinder and scaled it to the proper size using the control handles on the model.

With the cylinder finished, we lowered our pumpkin model on top of the cylinder so that they overlapped. To ensure that the hole works in printing, we extended the base of the cylinder past the workplane using the control handles. Then with the cylinder selected, we changed it from "Color" to "Hole" and grouped the pumpkin and cylinder hole together. This creates a pumpkin with the proper candle hole inside! 

Once you've crossed this point with your design, you can save it in TinkerCAD and download the STL file for printing. When you upload your design to the Polar Cloud for printing, we suggest you use a small "Infill Amount" in your Cura settings (5-10%). This will allow more light to shine through from your candle! Finally, be sure you have support material turned on to ensure your candle hole doesn't cause your part to collapse during printing. With those settings in place, you can press print and watch it go!

Once your design has printed, simply remove the support material and insert your LED candle! Take a picture of your design all lit up and send it to us, and we'll be happy to share your spooky creations. Best of luck to everyone in this challenge and have fun printing!

Home Fix-It Polar Challenge Winners!

Home Fix-It Polar Challenge Winners!

Let's get right down to it, here's our awesome winners for the Polar 3D Home Fix-It Challenge...

Winner - "Hook For Bags" by: Tyler Wos and Jason Muglia

This entry was an early favorite during the challenge due to its simplicity and effectiveness at such a common problem. Everyone has groceries — and whether you use tote bags, paper or plastic — at some point the amount one can carry easily becomes pretty limited. This design allows easy transport of bags from store to home and helps the user carry far more, without strain on the hands, in less trips. We definitely encourage folks to print a few of these out to keep in the trunk of their car, or with their grocery tote bags. We'd also suggest trying the design in some carbon fiber filament to really boost the amount of weight you can haul. Who knows how much weight one of these could take?! If you find out, let us know — print the file from the Polar Cloud here!

Runner Up - "Drainable Sponge Tray" by: Zachary Casto

This design was pretty interesting to the judges as it not only served an interesting purpose, but solved its problems in a subtle way. Disposable cleaning items like sponges generally don't have a "place to live" in the home, save for the edges of the sink. This causes them to not only build up grime faster, but also make the area they're sitting become as dirty as the sponge. By making a 3D printable storage area, the sponge can be set to dry on a cheap an easily replaceable 3D print that drains itself of water with its subtle geometric slope. And once the sponge is dry, it can be stored inside the tray, away from the view of guests, etc. We'll definitely be printing these out for our sinks — and you can print one out too, right here on the Polar Cloud!

Runner Up - "Backpack Clip" by: Aidan Moncelle

This backpack clip really intrigued us as it solved a personal problem for Aidan — holding drawstring bags (like gym or storage bags) closed and secure over his shoulders. But the real thing we appreciated about this design was the versatility of it. You can print this design and not only solve Aidan's problem but a slew of other around the home. A simple and durably designed clip like this is perfect for holding things all over a home. We've been printing these out and using them for hooking up lots of things where one might use a carabiner or ring hook. This is also another print that benefits from stronger filaments like carbon fiber. You can grab this awesome design here on the Polar Cloud!

...and as always, you can go check out and print all of the challenge entries for free here on the Polar Cloud!

Congratulations to our winners, we will be contacting you to send your winning filament soon. Thank you to everyone who participated in our latest challenge, the entries are always fun to print and test out! Please keep an eye out for our next, Haunted Halloween Challenge starting shortly!

iPhone Accessory Challenge Winner!

iPhone Accessory Challenge Winner!

We have a winner! After a successful iPhone Accessory Challenge, we've been able to select some great iPhone Accessories for the community. First — our two runners up — winning 3, 250kg rolls of filament each are:

Meghna Iyer with her Hexa Holder!

We liked this design for it's simple functionality plus it's beauty even when the phone isn't present.

 
 

Megan Callow with her iPhone 7 Stand & Cord Holder!

We really liked this sturdy design for its attention to cord management while viewing videos.

 
 

*DRUMROLL* ...and the challenge winner of 6, 250kg rolls of filament is... *DRUMROLL*

Ben Shuman with his iPhone 7 Panorama Adapter!

There are plenty of reasons why we like this design, but we'll let Ben explain why this design is so cool! In the meantime, go download it here.

This is a panorama adapter designed to fit the iPhone 6 or 7. By inserting your phone and placing it on a tripod, you can take panoramic pictures and minimize parallax errors for nearly perfect photo-spheres! This design works because it places the vertical pivot ('ears') and the horizontal pivot (tripod mount hole) in alignment with the phones camera lens. 
This version of my design has a slight change around the camera lens area to make it compatible with the the iPhone 7 as well as the iPhone 6 & 6s. 
You can use the same phone with Google Cardboard and make a virtual view of your school, Boys & Girls Club or other hang outs. And by using the Google Streets App you can make and link multiple photo-spheres to create a full virtual tour of your favorite locations! 
This device consists of two parts - The Base and the Phone Adapter
While you can print out both pieces together, you may have better luck printing individually (and then change colors for added flair!). If printing individually, the middle (Phone Adapter) needs supports for the little pivot 'ears' that allow it to hang from the frame. Also, the tripod hole in the Base has threads printed into the case, but it is a good idea to chase the threads with a 1/4x20 tap to clean up the hole for easiest use. 
 
Check out the cool panorama Ben made with his design! Now you can too!

Back To School Challenge Winner!

We'd like to congratulate Bethany Jones, a teacher at Mason Middle School, on winning our Back-To-School Polar Challenge — with her twisty pencil holder design! We like it because it not only is a fun and functional design, but it takes advantage of the crazy geometries that can be made available only through 3D printing! 

 
 

You can find the object here on the Polar Cloud for download and we encourage you to try it out for yourself! We gave it a whirl in our offices, and love having it around

Bethany will be receiving 3 filament rolls for her winning design and we can't wait to see what else she and her students print with it! You may have noticed Bethany and her students on Twitter printing up cool items like a multicolor Mickey Mouse egg, Rubik's Cube Holder, and Golden Snitch! (see photos below) You can follow Bethany and all the cool things her students make on Twitter, @bethany_jones4.

As always, you can find the latest updates and challenges right here, or on the Polar 3D Facebook and Twitter page. We'll be announcing the next challenge very soon, so stay tuned!
