Solidoodle Snap in Spool holder.

thingiverse

For rapid spool changes on a Solidoodle printer, use these snap-in spool holders that eliminate the need to undo screws. Available in 1.25in and 1in rod sizes, these securely attach spools without popping out during movement, enhancing convenience. To set up, print one left and right holder for your chosen axle size, followed by two small and long brackets. Secure the brackets using appropriate screws, load the axle with spools, and snap into place. Enjoy!
