'Prusa' Filament Roller

Description

Filament Roller, this design uses 4x 626Z bearings and two carbon fibre tubes to join the sections. I originally design this using rolled carbon fibre tubes that I had spare as it looks far superior but yo can use the STLs to print your own tubes. Mounts are 100% infill no raft, no support Sides are 20% infill no raft, no support I used superglue to hold everything together, this makes it incredibly rigid. ###If you want to use carbon Fibre ------------------------------------------ The larger tube is 15mm I/D , 16mm O/D, 97.60 mm long. (I/D & Length Important) x2 The smaller tube is 8mm I/D, 10mm O/D, 93.50 mm long. (O/D & Length important) x2 Optional Filament clamp * There is an option of printing the smaller of the two filament clamps, you should only need one for the front. You should take one of the larger tubes and cut it down to 2x 45mm long tubes. Fix the clamp in the centre and use this at the front. I would suggest angling the entry hole up at 45 deg. Filament clamps are 20% infill no supports ###[Printed Tubes If you don't have Carbon Fibre] ------------------------------------------ You can choose to print the tubes rather than source carbon tubes so I have included STLs for these, there are 3 sizes - the short large diameter tubes are for use with the larger front mounted filament clamp, the longer for use without and the long thin tubes are for the rollers. Tubes are 100% infill no raft, no support ###Optional 6800 10x19x6 mm Bearings ------------------------------------------ You should also be able to use 6800 10x19x6 mm Miniature Metal Ball bearings as well, this would mean the smaller tubes would slide in to the centre for the bearing and therefore would need to be about 14mm longer to account for this (cut to fit). It is easier to use these with the carbon tubes. If you do choose these then you would not need the mounts.
