I saw some problems with the originals, so here's my fix. Changes: • It's all one part. No assembly screws, and a nice big open space for accessing the single fixture screw. • It fits the two types of dust filters on Thingiverse (the unit with two screws as well as the taller threaded version that I use). • Vertical structure has added support ribs - even with 20% infill this seems to be more than stable enough, keeping the part lighter. • Rear wire harness retainer is now intended to be a zip tie, not a separate printed part. I'd like to eliminate an extra part entirely. • Prints without supports. I'd like to: • Have the wire loom retainer be built in. • Make the filament dust filters swap out a little easier. Mine are a press fit so some improvement might be seen modding the filter itself. • Fix the unit so that when it's bolted up it cannot rotate freely.Printed around 25% infill at 0.20 layer height in PLA. No real instructions other than bolt it on and enjoy.
