The shaft from the gear doesn't fit into the lift base...

There are many factors that can affect print size. May be easier to drill out the hole if the shaft is too big.

Awesome design, well done! Do you think I'll be able to scale it down to 80-90% (trimming manually the motor shaft hole), since I have quite a few 1/4" bearings laying around? I'm thinking that if I print it as is, the 1/4" bearings will probably jam the wheel ...

Very nice, I've downloaded your STL's and now I'll try to print it.
Thank you very much.

Love the modular concept.
