PCB Spacer for CNC Milling
thingiverse
Simple spacers for PCB Cu boards when milling or drilling on cheap chinese CNC. Clicks into each other for customizable squares. Tighten down with M3 screws. I use these with my custom simple T-nut holders: https://www.thingiverse.com/thing:3725623 also available here. Use the "Link" part to connect several spacers together if you need a longer part. I have designed for my CNC2416 mill and FR4 Cu boards that are about 160x200mm. Source files available at: https://gallery.autodesk.com/projects/141797/pcb-bedholder-and-spacers-for-diy-cnc-mills
