Top Mounted Spool Holder for Mini Kossel

thingiverse

This is a precision-mounted spool holder. It's a robust variation based on http://www.thingiverse.com/thing:300553. Easy printing can be achieved on round Mini Kossel beds. Designed for seamless integration with 15x15 Open Beam Frame extrusions. The symmetry has been corrected, allowing you to print two without mirroring the second. Instructions Print two spool holders. Required parts: Four VXB 608 ZZ bearings Four m3 flat washers Four m3x8 socket cap screws Four m3 full nuts The bearings should fit perfectly onto the mounting posts. Mount both on one of the top frame extrusions with the bearing facing each other. Place the nuts in the top track of the frame extrusion, line them up, and secure the spool holders using the washers and cap screws.
