QChord QCard Door Fix

This is a fix for a common problem with Q-Chords: the super thin and weak hinge pin for the q-card door snaps off.

To fix:

1. Print this
2. Cut off any remnants of the two hinge pins as flush as you can
3. Glue the print to the door - hot glue is just fine, but you can go stronger
4. Run a 75mm, M2.5 rod through it, place the spring on the rod on one side too
5. Wedge into the posts on the chassis, pull back the spring, optionally secure it with a little blob of glue

The rods I purchased here worked for me https://www.aliexpress.com/item/32894702787.html
