Announcing the Winners of the Mechanical Design Challenge

Announcing the Winners of the Mechanical Design Challenge

Today we’re excited to announce the winners of the Mechanical Design Challenge! We had no shortage of excellent entries and the judges were challenged with choosing just three winners. If you didn’t win this time fear not, we just launched the Avatar Design Contest where you can win a Formlabs Form 2, Oculus Rift, Zbrush Core License, and a Mold3D course as the top prize!

Honourable Mentions

2016 Suzuki GSX-RR 1:8 Racing RC MotoGP Version2 by Brett Turnage

We were blown away by this RC Motorcycle by Brett Turnage and we’re working on making our own! The impressive mechanics, both in regards to the motorcycle itself and articulation of the driver, made this entry a top contender. 

3D-Zipper by Ronald Jaramillo 

We’ve seen a few printed clothing items before like functional chainmail, but this 3D printed zipper was a first. This design prints deceptively easily with few support structures so you can make your own! 

Step Clock by makit 

Makit’s 3D printed step clock is a great primer on electronics and programming. It makes use of two stepper motors for movement of the hour and minute hands and Makit has included full assembly instructions so you can make your own!

3rd Place

PistenBully 1:14 R/C by Supeso 

Supeso did an incredible job with the design, documentation, and presentation of this R/C design. Make sure to check out the design page for videos of the PistenBully in action! Congratulations on your win of a $100 3DHubs gift card. 

2nd Place

Hand-Screw Clamp by jakejake

This entirely printable clamp by jakejake makes use of a dual thread mechanism to output an impressive amount of force. Great job with the design and presentation and congratulations on your win of a $200 3Dhubs gift card and the Prusa MK2S Kit! 

1st Place

Fin Gripper (Robotic/Prosthetic Hybrid) – Mark VI by Black_Ram_Industries

The winner of the Mechanical Design Challenge is Black Ram Industries with their Fin Gripper design! An impressive number of iterations were completed to reach this fully-functional design. We’re looking forward to seeing what they make next with a Formlabs Form 2 and $100 Adafruit Gift Card. 

Special thanks to our sponsors: Formlabs, Adafruit, 3D Hubs, and Prusa Research

  • Luke Stanislas

    Thank you guys so much. I can’t believe I won especially against so many other great designs. This is amazing.

  • Ion Gurguta

    hello pinshapers want to open this thread to tell me if you really believe if the contests are really judged proper activation it is clear that each of us believe that our design is better than none is normal is in our way of being. I want to be clear that in the competitions that participated in none and I think my designs are the best but from this base I remember one that was about the accessories for the bike and there were a lot of very good designs but In the end I win a mobile phone holder if a mobile phone holder. (What is the novelty ?????). Pus I see my opinion is the following as I remember the mobile support I remember a very very good design on a remote braking system for the small bike, but that is not acer has won the first prize Novelty is a support of movil now we have participated in a contest of robotics, mechanics, electronica and everything that includes such designs that won the first prize ???? Because a design that has already participated in a previous contest for disabled people in the hands is true the design has changed a little since then is now more handsome. But according to the rules of the contest the design did not have to be participated in a previous contest and like these examples there are many who think about this ?????

  • kmfeff

    If the rules say you cant’ use a previously summited design, then I don’t understand. I think they were disappointed in the entries. I believe they were expecting much more exotic if you will entries considering the 1st place prize. they did take 2 1/2 weeks to judge it. That says something.

  • Ion Gurguta

    Thnks for your replay so your opinion is??……

  • brett turnage

    Go to instructables for competitions. Judging is more balanced.

  • Ion Gurguta

    I just see your designs are pretty awesome. A lot of days or weeks … putt in the motorcycle design. And just a honorable mention???? And the first place is a design that was participating in 2 contests????

  • Ion Gurguta

    I am not a pinshaper for competition I am here to learn like all. But for me it’s just unfair. Sorry if I am a little confused “maybe”

  • ekaggrat singh kalsi

    i dont see what is so mechanical in the step clock ,, it is just a box with needles and a cheap chinese mechanism. Hell my clocks are way more mechanical.. the judges have no sense what so ever!!

  • brett turnage

    it took almost a year to figure out how to make a working 3d printed RC motorcycle that drove like a real bike.

  • Black Ram Industries

    Wow… I will respond because I wish to highlight my hard work and efforts to those who don’t think that my work was a worthy contender.
    I started design on the Mark VI version over 6 months ago. I spent 3 weeks every night researching advanced industrial robot gripper designs.
    Once I found and studied the fin grip technology I made over 8 different prototype versions over 4 months (nights and weekends) which included everything from 3D printed silicone moulds trailing different durometers, thin wall sections with PLA & ABS materials, bearings and bushings, bending inserts for ribs both printed and metal and then finally flexible filaments.
    A lot of them didn’t work or were not easy to make and print. I have used an enormous amount of filament, silicone rubbers and gone through a lot printing time. Once I managed to get a good working design I then spent another month making it as simple to print (so that anyone could print and make it) as possible while still being fully functional, easier to assemble and more capable of grasping and holding objects than the Mark V.
    And after all this I give my designs for FREE for anyone to download so that it can be used to help others. This is not the same design or a more “handsome” version, it is a completely new robotic gripper configuration. You have confused this as a simple design when really its simplicity is hidden by the technical MECHANICAL knowledge and MECHANICAL DESIGN work that went into its making.
    You have done some really great design work on your models and I wish you all the best in future competitions. I do hope that one day you may win one, unfortunately you may find that on the internet when you achieve that success there will always be someone around to try and pull you down.

  • just_another_commenter

    This is why I don’t enter the pinshape contests. I’ve seen some of the other contests. You can put a lot of thought/time into a well designed project and it looks like the judges just randomly draw from a hat. Nothing personal to the winners, but just check out that bike as an examples. It actually DRIVES LIKE A REAL BIKE and it is an honorable mention?

  • Debra Nicholson

    I agree the bike is great

  • Po’Boy Joe

    I think those gripper fingers are kinda patented by Festo…
