<p>Design is similar to the single bracket mounting version - <a href="https://www.thingiverse.com/thing:4001842">https://www.thingiverse.com/thing:4001842</a></p> <p>This version will build on a 150 x 150mm printer and assembled using M3 or similar hardware to match the one piece bracket design. Currently in use on my Tevo Michelangelo printed in standard PLA; 5 outlines, 6 layers top and bottom, and 50% infill. Tighten hardware to snug and thread locker is also recommended on the bracket joining screws and nuts.</p> <p>This design is to mount on a 20x40mm Aluminum extrusion end used on most small printer Z-Axis to permit filament pull on the extruder to be more horizontal than vertical. I found there to be too much slipping on my Tevo Michelangelo even with changing out the OEM plastic junk extruder with an all Aluminum MK8 with 40 tooth drive gear.</p> <p>This almost zero (0) friction spool holder was part of the solution along with changing the 40 tooth drive gear to a 26 tooth on the MK8 Extruder.</p> <p>CAUTION: Depending upon the printer it might be necessary to add weight to the printer to prevent tipping due to the center of gravity change with a full 1kg spool on the roller.</p> <p>Original design files included in various formats - Fusion360 native files and STEP versions..</p> <p>Mk8 Extruder Drive Gear 26 Teeth Copper 11Mm X 11Mm: https://www.amazon.com/Extruder-Drive-Copper-Printer-Makerbot/dp/B074K45PZX</p> <p>Extruder Aluminum Feeder Kit with Spring Adjustable Bolt, Compatible with 1.75mm Filament for 3D Printer MK8 Bowden Extruder Frame: https://www.amazon.com/Extruder-Aluminum-Adjustable-Compatible-Filament/dp/B07KQ6FVS3/ref=sr_1_1?keywords=Extruder+Aluminum+Feeder+Kit+with+Spring+Adjustable+Bolt%2CCompatible+with+1.75mm+Filament+for+3D+Printer+MK8+Bowden+Extruder+Frame&amp;qid=1573921594&amp;sr=8-1</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>TEVO</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Michelangelo</p></div> <p><strong>Rafts:</strong></p> <p>Doesn't Matter</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.1-0.25 mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>25-100%</p></div> <p><strong>Filament:</strong> Any Brand PLA or PLA+ Any Color</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>5-6 outlines with 6 top and bottom layers for strength.</p></div> </p></p></p> Category: 3D Printing
