Re: Practical 3D printed parts

We designed and 3D printed a part to mount encoders, too!
It made mounting magnetic encoders in several places on the robot a lot quicker and easier.

If you look up my username on Thingiverse, you will find a 1/2 inch hex shaft-to-arm attacher that we used for a while.

Could someone post a picture of a 3d printed camera mount? Just looking for ideas.
Thanks

Here is ours. A simple angle bracket to hold the camera. Another part to hold light rings.

See here.

Sure they're practical. We've been using 3D printed wheels since 2010.

Re: Practical 3D printed parts

All of our 3D printed parts can be found on thingiverse in our 2014 collection: https://www.thingiverse.com/team2177/collections/2014

We have 4 distinct parts for this year:
Battery plugs
These have "Charged" and "Not Charged" on them, allowing you to have plugs in every battery while still indicating the state of the battery. Bonus points: Print the "Charged" in one color and the "Not Charged" in another!

Pneumatic storage tank holder
Designed to hold 4 tanks in a square pattern, can also be adapted to hold 2 stacked.

Ball Roller
We designed a roller for a 1/2" hex shaft. It has a curved surface to match the ball, and is 12" long (printed in 3 segments). Please note - you'll want to put something on it, like spray rubber, to aid in traction with the ball!

Winch spool
We're using a winch to pull our catapult down, utilizing 1" webbing. The spool prints in two parts, is designed for a 1/2" hex shaft, and has recessed 1/4" holes to secure everything together. It also comes with a guide that fits over the spool (with clearance holes for the 1/2" hex shaft) and helps ensure the webbing gets placed on the spool to avoid tangles. Obviously, it has a lot of compression force on the winch when it works, so we recommend using 100% infill!
