Spool holder for Ender 3/CR 10

thingiverse

Here's a standalone spool holder designed specifically for Ender 3 users, boasting the significant advantage of minimizing vibration and ringing caused by the printer itself, thanks to its clever separation of the heavy spool. To create this ingenious solution, you'll need two bolts and t-nuts, which are conveniently sourced from spare Ender parts. Crucially, support is only necessary for the holes drilled specifically for the bolts and t-nuts. The design calls for a flat print (third image), ensuring a seamless integration with your Ender 3 setup.
