MP Select Mini Improved Spool Rack

thingiverse

This is a custom designed filament spool bearing rack made specifically for the Monoprice Select Mini 3D V2 printer. I created it because the feeder motor's loud clicking noise was annoying when trying to rotate the spool against the stock metal rack. This design fits over the existing rack, requiring no modifications to the printer itself. It is designed specifically for Monoprice brand filament spools and allows any spools with an inner diameter of 4.5 cm or more to slide right over it. The spool width is a generous 7.7cm. This custom bearing rack uses two standard size 8x22x7w Universal bearings, available at Newegg: https://www.newegg.com/Product/Product.aspx?Item=9SIABYB4R69069&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_- The print includes the main piece and two optional end caps, depending on whether your bearings fit snugly. Mine didn't need these extra pieces since the bearings pressed in securely after printing. Here are the dimensions you'll want to match in your slicer before printing: Length: 93mm Height: 45mm Width: 29mm Make sure to double-check that your slicer matches these exact dimensions, or everything won't fit together properly.
