Dremel lathe remix

Micro-lathe, great for dremel

Also added a rail slider system to mount this to, idea is to screw the main part to a piece of wood, etc., and the slider piece moves in and out for mounting lathe pieces of varying lengths... This slider system is only compatible with the new wider and reinforced blocks here, and not the original parts

Also upgraded tool and bearing fixtures to fit better in bearings without risk of sliding around (depth-wise).

All the nut holes have also been enlarged to fit #4-40 nuts & bolts because my local hardware store doesn't have M3. For the slide locks and lathe mount block screw-in piece holders I used #6-32 1/2" bolts

Changes from original design (only changed parts shown, all other original parts are still compatible):
- Adjusted bearing block to fit 608 bearings better, but still snugly. They are removable (not vice/press fit), so if you want them locked in, just use a little glue or acetone smoothing around the edge as glue
- Adjusted bearin
