PCB marker tool head with spring option.

I recreated this part based on "HyperCube CNC Toolheads" by Tech2C.

You will need:

screws:
- 1 x hex M3 20mm (hex head max 5.4mm inner diameter)
- 2 x M3 12-15mm
- 2 x M3 8mm (mounting screws)

nuts:
- 3 x hex M3
- 1 x rectangle M3 max 5.5mm

rails:
- 2 x fi8 x 54mm

linear bearings
- 2 x fi8 x fi15 x 23-24mm

In the base part, there are 2 sets of mounting M3 holes with hole spacing 24mm (in my printer head mount there are M3 holes with that spacing).
I'm using the bottom
