Wall mounted spool holder

This is a wall mounted spool holder

It required a total of 4 mollies and 4 screws + whatever kind of rod ( 2 cm in diameter or less ) you can find

The caps are glued to the rod to prevent sideways movement and ensure that the rod stays on the supports

This version is not suited for 3d filament as it is ( not enough clearance ), It can be stretched or printed larger should you really want to use it anyways.

I will be designing a version specifically for 3d filament
