My modifications to Mape's PCB Drill press.

1. The 8mm smooth rods I found were 100mm long (and actually measured 103mm) so I made the frame a bit taller.
2. I added 608 on the axle so the threads don't turn against plastic.
3. I tightened the holes for the smooth rods - I'd rather they be a tight fit than have any slop.
4. I added holes and nut traps for 2 M3 screws at the front of the lid to clamp the the smooth rods in place - with the tighter fit this helps pull it together.
5. I added a clip to hold my chuck key on the side.
6. I redrew the lever handle and attachment so they have printed threads and the M8 all thread just screws in place.
7. I drew a printable base - but then just used it as a pattern to make one from wood with some printed feet. I've included a PDF of the pattern.
