Remix of X,Y,Z carriages for the DIY Dremel CNC design and parts by Nikodem

thingiverse

I've modified the original X, Y and spindle carriages to have slightly larger linear bearing holes (for tighter tolerances with my printer and ABS filament). The original X-carriage design had a clamp type fixing for the 12mm linear rods, this was prone to breaking if crushed / over tightened. Replaced the 'clamp' with a through-hole design where the rods can be secured by grub screws I also modified the lead screw holes so they only have fixings on one face, the other face has a larger hole to allow a anti-backlash nut to slide inside. Fitting can be a little fidgety, but it does work. I reamed the holes (instead of filing) in post-production for more accurate hole diameters. Added a Z-probe connector to the frame, RCA connector for ease-of-use. Found some feet in one of Nikodem's Fusion files, modded it to countersink. Also created a middle leg for added support of the frame in the center. Optical end-stop mount was retrofitted to the spindle carriage and Z-axis carriage as I'd already printed those parts previously. I will re-design them to integrate into the carriage prints in the future if I ever need to re-print them. The optical end-stop trigger was remixed from [Anet A8 optic Z-endstop](https://www.thingiverse.com/thing:2512192) by [Sagatxx](https://www.thingiverse.com/sagatxxx/about).
