TOM X-Axis Follower - Recessed Bearing Bolts
Derived from
Description
Added a recess on the back side to insert the bearing bolt heads into. That way you can put nuts on the bearing side to keep them secure instead of relying on drilling/tapping the plastic. I also made the default for the dimensions of 693 bearings. The comments in the scad script show you what to change for whatever bearings you have. Note: 624 bearings are too large! So anything under that should work.

I already tried 624s and they are too large. It will not work with 624! My version with 623s is perfect-so good -my platform was still dead level after the mod without touching any adjustments.
Awesome work, thanks! (And to Ed and Carmiac too)
I spotted something odd - just after the comment for the trapped nut recess, there are two cylinder operations, one of them just seems to make a tiny flat coin shape that fits entirely within the nut recess. Removing it entirely seems not to affect anything.
Also, I am trying to make the nut rece
sses hexagonal, via $fa=60, but it doesn't seem to work. Any ideas?
Nevermind, I just realized that the recess is for the bolt head, and the nut goes on the other side.
Great design btw, I'm using it now, it has transformed my ToM.
Try making a circle and forcing it to be 6 sided. Easy way to make a hexagon in openscad.
