Monster PCB Drill - No backlash

I redesigned the carriage and guides, added 4 pieces, LM8UU left the rest as is, the gear and handle fit. I didn’t print the top, but I needed to, I happened to have a shaft with a longer thread, so I’ll soon finish the top.

Do not glue the upper washer that is on the shaft, otherwise you will lose the ability to adjust along the Z axis
