3D model description

I had seen different spool holders and wanted to combine a lot of what I saw into what I wanted. I wanted something that would attach to a 2020 rail system, could be mounted in different configurations, and utilized a bearing for a smooth action. This holder combines a 3.5 hard drive bearing and the parts you print and 5 total screws and 2 t-nuts.

On my application, I used M4 x 8mm screws and M4 t-nuts to secure the mount to the rail. I reused the screws from dissasembling the hard drive and the bearing to assemble the rest. Assembly should go in this order: 1) M4 screws and nuts attached to printed mount. Leave nuts loose. 2) Mount hard drive bearing to printed mount. 3) Attach mount to 2020 rail and tighten it down to secure it. 4) Attach screw to exposed side of bearing and secure with screws. Rotate the bearing to see the exposed screw holes on the side of the mount. 5) Attach spool and secure with printed nut.

The advantage of this design is that it is useful for many types of spools/filament and it can be mounted in any orientation on the 2020 rail. Also, please rotate the mount 180 degrees so that it will be printed with the circles indentations facing up.
