Ender 3 Filament Double Roller Guide

!!Working but still not perfect!! This is a WIP double-rollered version of the [robathome's remix](https://www.thingiverse.com/thing:3061551). It was created using modeling software, so some imperfections are to be expected. Another guide for a doubleroller can be found on thingiverse at [klingler's version](https://www.thingiverse.com/thing:3389293). One of my first attempts at using modeling software, so please bear with me and offer feedback. Known problems exist: - There is not enough room for the roller if you push it where it needs to be (see the gaps in the picture). - The models are probably 10 times larger than they should be, so import them at a 10% scale. M4x25 bolts were initially used but proved too long, so more nuts were employed instead. Despite some initial issues, this doubleroller is working surprisingly well. Some valuable hints to keep in mind: - I recommend using the ring and spacer from robathome's remix: [robathome's remix](https://www.thingiverse.com/thing:3061551). - You will need four spacers and two rings. - The rings needed to be scaled down to 29.4059 in both X and Y dimensions, without affecting Z (the original size of the rings). This allowed for proper fitting of bearings onto the rings (and some extra force was required at one point). - Before you begin assembling the doubleroller, get an M4 bolt, an electric screwdriver, and experiment with spacers to make assembly easier. - Tightening the side holes is also a good idea.
