Prusament Filament Roller

#UPDATE 13/1/19 Sorry to all who I have tried printing this and then realized I messed up the instructions on using supports. The side part does indeed need supports because there's a cylindrical part that extends out from the side. This has to be printed with the right orientation due to the hex-shaped holes. #UPDATE 13/11/18 I've uploaded a new version of the side plates that should fit 608s 22 mm bearings, although I don't have any of these bearings so I haven't been able to test it yet! For some reason, the STL is really big at 19MB - not sure why as I just edited the original - I'll re-do it at some point and re-upload. You will need to use 8mm bar with this version. #UPDATE 9/11/18 Apologies but in my hurry to upload due to so many people asking me for STLs, I inadvertently uploaded the STL with the side pieces lying down. It'll be really difficult to print them like that, so they should be printed in their normal position and I've updated the STLs to reflect this! Prusament Filament Roller: This design was based on the new Prusament filament reel. It uses 4x 626Z bearings and two 6mm steel rods. NOTE: If you're using the 6mm steel rollers, then you only need to print the 2x side pieces and 2 of the larger tubes! You can also use carbon rods like my other design https://www.thingiverse.com/thing:3033892 I originally designed this using rolled carbon fiber tubes that I had spare as it looks far superior, but you can use the STLs to print your own tubes, although they don't roll as well as the steel or carbon rollers. Mounts are 100% infill with a raft and no support. Sides are 20% infill with no raft; supports are needed! Tubes are 100% infill with a raft. I used superglue to hold everything together, which makes it incredibly rigid. If you want to use carbon fiber: The larger tube is 15mm I/D (Inside Diameter), 16mm O/D (Outside Diameter), and 97.60 mm long. The smaller tube is 8mm I/D, 10mm O/D, and 93.50 mm long. Printed tubes if you don't have carbon fiber or steel: N.B. These don't work as well as steel or carbon rollers so they are not a preferred option. You can choose to print the tubes rather than source carbon tubes, so I've included STLs for these - there are three sizes: the short large diameter tubes are for use with the larger front-mounted filament clamp, the longer ones for use without, and the long thin tubes are for the rollers.
