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 one set.
You can use optional light spring 4.2mm x 23mm, but for PCB printing it is not necessary.
In my case, the tool head positioned itself at the bottom.

Also added 2 parts:
PCB holder that helped me to hold properly PCB during print.
Z axis modifier that moves up Z zero position about few mm to secure printer hotend during moves over thick PCB. Slide that modifier onto Z axis switch arm if you need that.
