Kossel Mini/XL spool holder 608zz bearing

This is a universal top mounted spool holder for the kossel mini. It is designed after the bio hazard symbol. I designed it to require only one 608zz bearing (a set of 8 only costs $5 on amazon). The spool spindle is made with a step design to fit two of the most common spool sizes (at least that I have come across). you need to print one of each except for the bracket which you will need 3 of.
