Filament Spool Holder for Prusa Mini

prusaprinters

<p>Filament spool holder is mounted on the top of the Z-axis of the Prusa Mini printer. Holder itself is printed from PLA, all parts around ruller from PET-G.&nbsp;</p><p>To ensure better printer stability (when full spool is loaded) use “heel” under Z-axis. I created it as small as possible (just cube to be placed on bottom end of Z-axis ALU profile).</p><p>To complete the holder use M6 threaded rod - cca 110 mm length. It's suitable to glue it to plastic part for better strenght. &nbsp;</p><p>Roller use two bearings 8/22x7. I used original bearing 608Z from spool roller. &nbsp;Roller is created from two identical parts and should be glued (but works fine without glue, just assembled). Is optimized for “standard” 1kg / 80mm spools (Prusament, Verbatim, ….).</p><p>When the filament is placed on the top then PTFE pipe from extruder should be bent upwards. Then is better when filament sensord is mounted and oriented to up.&nbsp;</p>
