Easy mount for Spool holder

An easy to mount filament spool holder

I use the spool holder designed by Rodamyot at ./thing:3502973 on all my printers. the only problem I have ever had was getting the thread tight with the bearing surface point exactly up. The original designee is simple elegant and ease tp print I have simply redesigned the screw cap so you can get 2 or 3 screws to line up on 20x20 20x40 etc.
