Finished most of the cad, just need to clean up tolerances and split a few parts. Here’s what I did:

• I made the rings for the gearshifter bigger because the gear shifter mount on the lead screw was hitting the center 1:1 gears. This caused lots of issues with sketches breaking so I had to redo those.
• I had to change the gearing for the last stage. The 1:1 gears were hitting the bearings so the only solution is to move the bearings further from the center, hence change the gear ratio. This also caused tons of problems and I had to redo a lot of the parts again, especially the gear shifter mount that mounts onto the lead screw.
• I added cutouts onto the blue part (it’s gray now, but the one that houses the bearing that the dog clutch goes on. The blue parts used to be hitting the 1:1 gears but now it clears by like 0.5 mm.

I’m still deciding whether I want to assemble this or not. I can’t figure out the 1way bearing based thing, and I’m starting to feel like it’s fundamentally impossible.
