I wanted to design a spool holder that could be mounted on any shelf or table not just 3d Printing nerd’s while still being simple, easy to use, easy to move and print without supports.
And that is exactly what I have done. This elegant design clamps down onto objects like shelves firmly and allows you to easily take filament on and off without having to move it. If you use the smaller clamp it can firmly clamp down on objects up to 40 mm wide and with the bigger one it clamps onto objects up to 60 mm wide.
It is modular and you can quickly screw and unscrew parts to suit the new object you are mounting it on. I have tested and used all the parts myself and it will be my new everyday spool holder.
For 3d printing nerd’s shelf all you need to print is the “spool holder C clamp 40mm space(recommended)” and the “spool holder bolt 55mm thread”
I recommend printing the walls a bit thicker than usual to maximise strength on the bolts.
