Ender 3 Pro Top Mount Spool Holder

thingiverse

I remixed this from [HUNMU's spool holder design](https://www.thingiverse.com/thing:3081267) while changing the lockup mechanism to [Deian's spool mount](https://www.thingiverse.com/thing:3866438) so I could keep using [LilTrublMakr's front-extrusion mounted LED light bar](https://www.thingiverse.com/thing:3272248). I also added [Holspeed's roller guides](https://www.thingiverse.com/thing:3052488) to keep the spools centered. On the bearing mounts themselves, I changed from two small dovetails to one large one, for ease of printing the extrusion mount, and added strength. I extended the bottom edge of the bearing mount so I could include a reinforcing and locking notch that will fit around the extrusion mount when not under load, but when the weight of a spool is on top, any deflection will be supported by the extrusion mount and also keep the bearing mount from shifting (which they shouldn't do because it's a tight fit, but very manageable. I had to do a slight amount of filing on the smallest part of the dovetail edges on the bearing mounts just because of my printer.) To print this, you'll need one Extrusion Mount, 4 Bearing Mounts, and 4 Bearing Guides. No glue etc are necessary, everything snaps together snugly at the bearings. This was my first really involved project in TinkerCAD, learning how to take things apart and recombine them how I wanted them. Hopefully someone else will make and enjoy it as well! I tried listing this as a remix of the things mentioned above, but Thingiverse's search-for-remixed-thing function isn't working.
