Pattywac Dueling Design Giveaway Winners!

Thingiverse user Pattywac has been running some pretty amazing design giveaways recently.  By pooling his own money with that of other Thingiverse users and coming up with interesting challenges, we’ve seen some pretty awesome results.  Who did Pattywac choose as the winners?  Well, first, a message from the giveaway sponsor himself:

I’d like to thank everyone for entering.  It was a great turnout and there were some awesome designs, it really was hard to pick the winners.  Thanks again to TwoTimes for more than doubling the prize pool.

Anyone that is willing to donate to the prize pool for the next Design Challenge is free to join the discussion in the Makerbot Google Group forum.


MakerBot Improvement Design Giveaway Winner is…

Z Axis Extender Kit for Makerbot Cupcake by Zydac

Z Axis Extender Kit for Makerbot Cupcake by Zydac

The Z Axis Extender Kit for Makerbot Cupcake by Zydac!  Pattywac said this was a tight race (between community likes, # of copies out there, and printability on the makerbot) but the extender kit won because it goes a long way (pun intended) to improving the Makerbot.

Rubber Bands Design Giveaway Winner is…

Rubber Band Gear Mechanism by Skimbal

Rubber Band Gear Mechanism by Skimbal

Skimbal’s Rubber Band Gear Mechanism!  Pattywac said he chose this one because it had over 40 likes by community members and it has a good future for use in other projects.

Congratulations to Zydac and Skimbal!  Thank you to Pattywac and Twotimes for posting the design giveaways, putting up the giveaway dough, and judging!  I can’t wait for the next one!

    Am I the only one who noticed that the gears are completely useless. They gear the rubber bands potential energy up and then down and then up, completely wasting all of the energy. And what are the extra two gears just stuck in the middle for? It is nothing more than BLING factor that one. Any one could have stuck a bunch of gears together and made them spin using rubber bands.

    This is an open community, so someone could use those gears for something if they so choose. What would you use them for? I say put up or shut up. I’m not trying to be mean, I’d actually rather you build something with it.

    Jestin I would not use it for anything as from an engineering stand point it would be more efficient and do the job better if it was just the first gear and rubber band.
    Any of the following should have won. They were all made by people other than the designer because they were usable.
    They were all made by people other than the designer because they were usable. NOT JUST BLING BLING to sway the simple minded. Anyone could have stuck a few gears together and made them turn.

    I agree with Jestin @Guest. It’s much harder to improve than critique. By all means design a better one and post it, the files are posted.

    Luis a better one is as simple as remove the redundant gears that go from gearing up to gearing back down. The entire mechanism is a waste of energy. The First part makes sense, the rest is just for show or maybe he has something in mind that he is keeping to himself. Either way even he didn’t answer the questions on the post about the gear ratios, probably because he knows it is all for show.

    The contest never said anything about the mechanism needing to do anything. Also, on all pendulum clocks there is a weight gear train to step down the force of the weight so the clock will run longer between winds. There is no reason that Skimbal’s setup couldn’t do that. Lastly, that was a contest run by another thiniverse member, if you have an issue with the way it ended up, post your own contests and judge them however you like.

    You could also take the mechanism and make your own frame to rearrange the gearing to whatever you like. What’s the point of having a makerbot if you don’t make you own stuff. Make as many derivatives as you like.

    @Guest: I would disagree with your observation.

    If you notice in the video there’s a red mark on the main gear. As Skimbal cranks you see that mark rotate maybe 1.5 times. However, he turns the crank to charge the mechanism nearly a dozen times. I would guess the overall ratio to be around 1:8.
