Monoprice MP Select Mini BB Spool Holder

thingiverse

At what point does something stop being a "remix" and become its own thing? I'm not sure, but this design incorporates elements of thing 1636941, thing 1989704, and my own work added in 123Design and TinkerCAD. Here are the links to the original items: MP Select Mini small spool holder by rixkix:http://www.thingiverse.com/thing:1636941 Fillament Holder (For Kossel Alt) by Homexperts:http://www.thingiverse.com/thing:1989704 It's a remix? A mashup? I'm not sure, but I can't take sole credit for a design that's more other people's work than my own. With that said, there are tons of filament holders for the Monoprice MP Select Mini 3D printer, and none of them met my expectations. Some were close, some were only for "mini" rolls, and some just didn't work well. This holder is about the same size as the stock filament holder and uses the factory mount. It has ball bearings that allow the filament to roll out freely, guides to keep the spool in place, and even features the Monoprice IIIP logo when it's mounted on the printer. When you print this with Simplify3D due to its excellent supports, it creates the best results and they come off cleanly. In my opinion, Cura always left behind a mess that was hard to clean up. Keep this in mind when choosing a slicer for this piece. You'll need 2 x 608zz ball bearings for this design to work at its best. It works without them too, but I highly recommend using the ball bearings. Edit: At my friend's suggestion, I tried something new and was surprised by how well these 3D printed bearing shapes worked - not as well as real bearings, but surprisingly well: http://www.thingiverse.com/thing:325847 There are four files to choose from: MP_mini_BB_spool_holder.V1.0.stl - The original version that's somewhat narrow and only works with some spools. Flipped_MP_mini_BB_spool_holder.V1.0.stl - The original version flipped upside down for fewer supports. MP_mini_BB_spool_holder_20mm_extended.stl - A modified version with 20mm extra space for larger spools. MP_mini_BB_spool_holder_25mm_extended.V2.0.stl - Version 2.0 with 25mm extra space, but overall length shortened to 120mm so it will print on the stock mini bed. See the images for a Cura screenshot that shows how to align it for printing. Note: If you're confused about which version to print, try #4. Sorry about all the different versions - I'm trying to help people out with their specific needs.
