M3D Crane Quad Fusion Individual Spool Holder

thingiverse

Thanks to M3D Quad User Brendan Rose for creating this file originally. I loved the design and felt it could be used for individual spools with 608 bearings. M3D's Quad really does its best when the filament being fed into the unit has little to no restrictions spinning. This design 100% helps with that, and I'm hoping the more people upgrade to this will add life to their stock motors. For added structure, I've included a 2020 rail and a mounting bracket to be installed on the right and left top sides to extend the top rail. Depending on the size of your rolls or if you are Quad or Quaden users, you may or may not need to extend the rail. I used M3 screws and nuts on the top to mount the spool holders and my Quaden motors. I used M4 screws and nuts on the side support for the 2020 add-on. 608 bearings slide onto the insert nubs and should easily slip and lock into place. With a little pull on your spool, they will easily pop out for filament switch-out. Afterwards, I drilled a small hole inwards on the nubs and added a washer and M3 bolt to keep the bearing from coming off, but that's not needed. To make the spool rod, I have holes included to connect everything. I cut a piece of filament, fed it through the holes, melted one end with a light, and slid it down into the hole, letting it cool. I did the same on the other side, being careful not to burn myself. You can use a knife or something metal and flat to flatten down this spot while it cools down. Glue can also be used. I used supports on these and printed at .2mm. Below are the things I bought to use with this project: iExcell 960 Pcs M3 Screw Kit - https://www.amazon.com/gp/product/B07HQC1CYF M3 Slide in T Nut Tee Sliding Nut for 2020 - https://www.amazon.com/gp/product/B01GCDG2QE Sliding T Slot Nuts 2020 Series M4 - https://www.amazon.com/gp/product/B07YCP1RPV M4x8mm 12.9 Alloy Steel Black Hex Bolt - https://www.amazon.com/gp/product/B06XWQRX2N 608-ZZ Ball Bearing - https://www.ebay.com/itm/608-ZZ-Ball-Bearing-8x22x7-Dual-Shielded-Metal-Chrome-Skateboard-608Z-10-QTY/303104406374
