Prusa i3 Spool Clamp

Prusa's base spool holder has much space to filaments, you can use this clamp to restrict unwanted movements of filament cartridge. I've designed it because of failed print by new filament rolls wrong and filament mess. You can use filament guide to solve the issue I've mentioned before but I've faced that issue even I've using filament guide, so I decided to make clamp to resist free and unwanted movement of filament cartridge.

Update (16-June): Added 20 and 10 mm thick versions. I've using only 1 piece of 30 mm version of this clamp for my printer spool.

P.S. My printer is Prusa i3 Mk2S
