prusaprinters

<h3><strong>Necessary commercial parts</strong></h3><p>4 <strong>stainless steel</strong> “608” bearings.<br>These are the same as the spooler bearings that come with the Prusa MINI.</p><p>8 cap screws (M3-15 or M3-16)<br>8 nuts (M3)</p><p>Foam rubber sheet with adhesive on one side.<br>Recommended thickness: 2mm to 4mm.&nbsp;<br>Prepare four pieces cut to 16mmx14mm.<br>Affix these to the bottom of the spooler.</p><h3><br><strong>Notes on assembly</strong></h3><p>Each bearing holder has a specific mounting point. Please check the imprint on the printout.</p><p>Make sure that the C-ring is inserted in the correct direction. (Please refer to the attached figure.)</p><p>When inserting or disassembling the C-ring, be careful not to injure yourself as it may pop vigorously.</p><p>Install all bearings first, and then join the left and right frames together.</p><p>No rafts and supports are required for this printing.</p><p>&nbsp;</p><p><i><strong>*Important Notice</strong></i><br><i>Some users have reported that the screws are difficult to insert.</i><br><i>This may be due to individual differences in the 3DP. For this reason, we have prepared a screw with a larger clearance as an option.</i><br><i>Normally, please print "<strong>Screw_knob_Flex_0.2mm_PETG_MINI_1h47m</strong>" for the screw. If you have trouble getting it in, try "<strong>Screw_knob_Flex(clearance)_0.2mm_PETG_MINI_1h49m</strong>".</i></p><p>&nbsp;</p><h3><br><strong>Print settings</strong></h3><p>Since the threaded part is delicate, please print with "0.2mm quality".</p><p>The filling rate should be at least 30%.　</p><p>Use PETG or PLA filament. PETG is recommended in areas with high temperatures.</p><p>The recommended infill setting is gyroid or rectilinear.</p><p>The screw knob must be printed independently. This is because when printing with other parts, the screw part may be slightly disturbed.</p><p>When freshly printed, the screw may get a little stuck. Therefore, it is recommended to run the screw back and forth several times.</p><h3>&nbsp;</h3><h3><strong>About Donations</strong></h3><p>If you like this spooler, please donate the equivalent of a cup of coffee.</p><p>I want to use it for the material costs spent until completion.</p>
