<p>(Another) filament spool holder for Prusa Mini+ (and similar).</p><p>It is mounted on the vertical axis of the printer using two T-slots (models provided) and uses two bearings from the original Prusa Mini spool holder (inner diameter 8mm, outer diameter 22mm)</p><p>Only other thing required is 8mm rod. I used 8mm aluminum rod but it probably can be printed too (haven't tried it).</p><p>Even though it has screw holes for fixing the bearings and aluminum rod, everything is friction fit together so no tightening screws are needed.</p><p>There are two variants of T-slot models: one meant for M3 threaded insert and another made for standard M3 nut.</p><p>Assembly:</p><ol><li>print the required parts: spool holder, base, stopper, two T-slots (either threaded insert or M3 nut variants</li><li>press fit the aluminum rod/pipe (8mm diameter, 90mm long) into the base. Model is also provided but I haven't tested it for strength</li><li>mount the base onto the vertical aluminum profile using T-slots</li><li>press fit two bearings into the spool holder, around 10mm into the spool holder</li><li>press fit the stopper onto the rod in order to prevent the rotating part to fall off</li></ol><p>&nbsp;</p>
