Re: Practical 3D printed parts

We printed several hex shaft couplers for the roller intake. Some of them broke, so we made more with tighter tolerances, more flexible material (Nylon) and higher infill. We'll see if the new ones break. We'll move to aluminum eventually, maybe.

We've made several encoder mounts, one of which I posted to CD. The rest could be acquired COTS if desired.

Some of the ideas we've had would require a non-linear profile for a roller to roll through as the launcher did its thing, and we'll 3D print them of the linear concepts ever get around to working at all.

LOTS and LOTS and LOTS of hex spacers for the roller intake.

Thought about making a clevis that would rotate a pneumatic cylinder 90 degrees on the tail so it rotates properly while also re-orienting the ports, but found a simpler solution with angle aluminum. For the roller intake, of course. (Can you tell that I led the roller intake subteam? )

Will poke at making pneumatic storage tank mounts since they tuck away nicely at a spot between the rollers (when they're down) and the frame.
