Droid Legs R2D2

thingiverse

Using the fab James Bruton 3D printed R2D2 as a basis, I've made edits for accuracy, thickened the legs like James did since they were slightly too thin, and added a 15mm strengthener to replace the makeshift bodge he used for stability. This is still a work in progress, so the final overall model hasn't been printed yet, but it seems very sturdy so far. The Legs are layered starting from 1 to 13; I've printed in ABS and acetone welded them together. Currently printing in three layers with 15% infill and it seems strong enough, but I'd recommend this as the minimum, especially if you're planning a static or mobile droid. Good luck! On May 21st, nearly all parts were added, the Booster Cover was modified (there are retrofit parts for those who've already printed it to glue on top). It's pretty much done now (I haven't printed the whole thing myself yet though). On 28th of May, I added the inner and outer shoulder hub so the legs can be attached. The whole thing is using 6mm threaded bar and nuts along with 100mm lazy susans in and out. Here's a video of the 2-3-2 conversation mechanism (manual at the moment but wanted to test the stresses on the feet and legs). I'm very pleased! https://youtu.be/O0uImKep5bk . I've also added some Magnet Holders and a modified shoulder plate. The Booster Cover is held on with two Magnets (10x4mm disc N52 disc), one attached to the Booster, the other to the modified shoulder Plate. I've also added Shoulder Post Magnet holders which attach to the back plate inside with two holders on the Shoulder (again glued) positioned where it won't interfere with the Leg Mechanism. I'll post pictures of mine once complete. Just working with the 2-3-2 and the battery cover can rub against the skirt, think I need a 4mm wider shoulders just for extra clearance. I will post a revised shoulder model and a post modification plate for the inside of the shoulders to save reprinting. Don't glue the shoulders to the legs for this reason. ** I added a Potentiometer bracket and arm for feedback to measure the leg rotation... Please note that the remaining design will be posted on Astromech.net (free to join and a great community). Also check out the Patreon page for links to the files. I always share all files for free and the original source files. I've now finished a complete revision of all the models, version 2 (all shared freely and openly), check https://www.patreon.com/mrbaddeley for links.
