Cone spool holder

thingiverse

My go-to spool holder design - a must-have for all my printers. This remix incorporates: 1. A mount compatible with a 2020 profile 2. The cone attaches on two 608 bearings, featuring a hole for a friction adjustment screw With two 608 bearings even the heaviest 3kg spools will rotate very smoothly. Occasionally, especially when using a new spool, excessive ease of rotation can cause filament to escape the spool and get tangled around the 8mm thread rod. That's why I added a simple friction adjustment system. Instructions: - Print cones without supports. - There are two rings in the base. Remove them with pliers after printing and make sure to keep the smaller one. The larger ring is a support, intended for disposal, while the smaller inner ring serves as a spacer that will be compressed by the friction screw (if used) to adjust rotation speed by adding friction with the thread rod - Insert one 608 bearing - it should fit snugly, if not use painter's tape or glue to secure it as no cover is included in this remix. - Insert the smaller ring into place - Add the second 608 bearing - Screw an M3x10 screw into the hole on the side and use it to adjust how easily it rotates after being attached to the rod. FreeCAD source code is included for anyone who wants to fine-tune sizes. Big thanks to the OA for this fantastic concept!
