Spool Holder

Açıklama

Spool Holder for Ender 3 (and similar printers) This spool holder is part of a bigger project — a 4-color Ender 3 IDEX modification. The design has been tested through static analysis and is intentionally overengineered to handle a wide range of spool sizes. In my own setup, I’ve used spools from 40 mm up to 70 mm wide. However, the holder is capable of supporting even larger or heavier ones — up to 5 kg with a 70 mm spool, or 1 kg with a 150 mm spool. If you like this project, feel free to check out my profile. There are other interesting builds there — including a $100 DIY laser cutter (v1 completed), which had to be paused due to lack of funding, but the full working prototype is still available to see. Thanks for your support!
