Finished tolerancing the holes, and I added the pulley to the input gear. I also changed the large bearing mount for the gear shifter and also redid the lead screw mount because stuff was hitting. Here’s what I did:

• I went through like 70 holes, compared it to the toleranced version that was assembled. Lots of problems happened when I had to oversize the holes. For example, the linear bearing holes on the gear shifter mount had to be oversized, which made the thickness of the wall like 0.8mm thick. I then had to go into my mastersketch and change up the dimensions which took a stupidly long time. Regeneration times are hitting near 2 minutes (300 features isn’t good, plus tons of dependencies, and so many dimensions that it takes up the entire sketch).
• I added the pulley to the input gear. I had to switch to a different featurescript because the one I was using didn’t have GT2. After that it was pretty easy, just had to cad the walls, chamfer a bit and boolean and bore it.
• The most annoying part was that the copper lead screw nut (on the mount) was hitting the 1:1 gears completely ruining the whole thing. I basically had to redo the shaping of the lead screw mount. I moved the copper part further up the part, keeping the standoffs at basically the same level. As a result, I had more space at the bottom for two screws instead of 1. Also, now all the constraints are fully dependent on the external parts, so there’s no random dimensions I did just to make stuff look good, which is good because it means if I change the gearing or something in the mastersketch, the mount should update accordingly. This also took a pretty long time and 2 min regeneration doesn’t help.
