Wanhao/Maker Select/Powerspec/etc Filament Holder with Guide

thingiverse

I've never been a fan of the standard filament holder on my Duplicator i3 Plus or the modifications I've seen because it only supports the weight on one side. As a pessimist, I don't trust holders where the spool just rests on bearings, so I worry about a kilogram of filament crashing onto the build plate someday. Like many others who couldn't find what they needed, I decided to create my own holder and added a modified filament guide from https://www.thingiverse.com/thing:1598317. To ensure smooth spool rotation and prevent it from hanging too low, I use spool adapters from https://www.thingiverse.com/thing:2102921. The adapter mounts to the printer with the stock bolts, but I may have used slightly longer ones due to its increased thickness compared to the sheet metal of the standard holder.
