20mm extrusion Filament Spool Holder for prusa i3 clones

thingiverse

This spool holder attaches to printers with a 20x20 mm extrusion frame, specifically my Max Micron Prusa clone. Print with supports for the bit at the top; mine warped slightly but it wasn't an issue. It's a snug fit, so I angled the tabs to make attachment easier. First, push the front on (the side that prints on top), then press down the back (the side that prints on the bed), and you'll see how it fits if you print it.
