I know what you mean about the tight wire routing. It’s doable… but requires adding some serous bend into the wires. I thought about spreading things out… but figured compact carriages main point was to increase printable area, so I left it really compact.
What area do you think sloping could help? I can get that added to the model. If I roll over this edge, and open up the pocket underneath… would that help?
All my heat inserts were M3. There are so many varieties of those inserts (different ID/OD/Depths). I should probably call out the ones I use with some notes. But I think I can increase the space below the inserts for thermal squeeze out during insetting. That being said my inserts are tapered m3 heatset… so I had almost no squeeze out during install.
For the bushings, I could make a version with larger bushing holes or some glue channels for epoxy-in methods. Just need to be careful not to get the glue in the self aligning portion of the bushing. Plus if the part is to dimension… it should have room for some glue as designed (See Picture)
