<p>Spool holder for MK3/S that centers the the spool. I've noticed that the wobble of the spool affects the extrusion, so i decided to do something to center the spool to spin smoothly.</p> <h3>Print instructions</h3><p>nothing special: i used PLA @ 220C/70C and 0.25 L.H.</p> <p>Important: In the G-Code, i've inserted a custom G-code commands in the start and end for insert/ retract 50mm of the filament.<br/> If you wish to use the original MK3s profile, just comment lines (put ; at the begining of the line or just delete it): 34, 35, 1462624, 1462625 and 1462626</p> <p>the lines are:<br/> line 34: G92 E0.0 ; eu<br/> line 35: G1 E48.0 F1000 ;eu</p> <p>line 1462624: G92 E0.0 ;eu<br/> line 1462625: G1 E-50.0 F1000 ; eu<br/> line 1462626: G92 E0.0 ; eu</p>
