Wanhao i3 plus or Monoprice IIIP filament holder upgrade

thingiverse

This is a spacer for the Wanhao i3 plus or Monoprice IIIP printer. It's designed to replace the poorly made original spool holder with standard 3/4" PVC schedule 40 pipe. I discovered that the original spool holder was too narrow to accommodate many of the wider spools of filament I had, and the stand was not tall enough for larger diameter spools. To solve these problems, I replaced it with a simple piece of 3/4" PVC pipe. What you'll need: * A 3/4" male threaded to slip adapter * A 3/4" female threaded to slip adapter * A 3/4" slip elbow * One to two feet of 3/4" PVC pipe * One printed copy of this thing This 'thing' does two main things. First, it fills some space between the two threaded adapters, allowing them to tighten up securely. Second, it fills the gap between the metal ring on the printer and the threaded portion of the adapters, preventing them from wobbling. To upgrade your spool holder, follow these steps: - Remove the existing plastic spool holder from the printer, leaving the metal upright intact. - Insert this 'thing' into the hole in the metal upright and attach the male and female 3/4" PVC adapters on either side. You can see a close-up of this in the second picture, where the grey piece is this 'thing' between the two white PVC threaded to slip adapters. - On one side, cut a short (2" long or so) piece of PVC pipe, followed by the PVC elbow and a 6" piece of PVC. This creates a right-angle mount for larger diameter spools of filament. Mount it so that the pipe is angled up slightly, allowing the spool to naturally sit against the edge of the elbow. - On the other side of the threaded adapters, attach another 6" piece of PVC for wider but smaller diameter spools of filament. The included pictures should make it clear what you're supposed to do.
