Advanced spool holder for Prusa MK series

prusaprinters

<p>This is a new designed spool holder for my PRUSA MK3S+.<br>When using the original reel holder, the filament&nbsp;is scraping noisy on the inner edges of the spool, depending on its positon and movement of the x-axis.<br>The spool swings as well forward and backward while the printhead moves and/or the extruder retracts.</p><p>My new design has a very small amount of friction so that the reel does not swing during operation. Due to the optimized position of the &nbsp;reel to the extruder inlet, the spool is unwound very clean. See picture.</p><p>The overall height (with spool mounted) &nbsp;is approx. 2 mm less compared to the original holder.</p><p>It fits tight to the frame while mounting but afterwards you can slide it easily to the left and right.&nbsp;<br>Please use a spatula (or similar) to help the bottom edge coming around the frame (like a shoehorn)</p><p>This works as well in case of removing the device….</p><p>I added the .step file in case of modifications are required.</p><p><strong>Update 21.05.2021</strong></p><p>Due to the several comments I added a second .stl file “Rollenhalter_hex05”.<br>This is slightly modified at the bottom edge and should come more easy around the corner of the frame.</p><p>&nbsp;</p>
