Filament Mount Parts for Mosaic by DocJames Oct 27, 2012

Description

These are some parts for a filament spool system I have been fooling around with for my Mosaic printer.

The mount is very solid, and can be bolted on to the Mosaic by using longer screws in existing captured nuts.

The Axles are inserted through the hole, and include one that can hold a smaller spools (designed with parts from, and to be used with, http://www.thingiverse.com/thing:8317), as well as an experiential "sealed" system that I tried for high-humidity climates where a short coil of filament would be placed in a plastic Tupperware container (with desiccant), which was then mounted like a spool, but where the filament was pulled from the inside. This worked, sort of, but was prone to tangles.

This is very beta, but I thought I'd put it out there as I am unlikely to work more on it, as I have moved on to larger spools and the spool holder like http://www.thingiverse.com/thing:21446

These were designed in OpenSCAD using Libraries http://www.thingiverse.com/thing:6021 and http://www.thingiverse.com/thing:8793

Instructions

Printout the Mosaic_FilamentSpool_Mount, remove the necessary bolts and replace with longer ones. Note that the clearance for the inset bolt heads is tight, you might want to drill them out or increase the tolerances. This part is prone to warping, so you might want to play with the bed temp and fans.

The axles mount into this piece, secured by the nuts. The offset spacer is also threaded, and allows the spool to turn with less friction, as well as prevents listing to the side on a loose press-fit spool.
