Here's a complete set of 3d printable parts for WPL C channel frames ( Usually the B series ).
Find them on Thingiverse:
There are a couple of different modular rear sections which provide possibilitys for future addons and accessories if I get around to it.
I expect they would be fine on all the other WPL, JJRC, Henglong & Fayee frames that use the C channel frames like the Q60 etc.
If there is anything you would like added - let me know and I'll see about including it and upgrading the set.
This should fit the following and more:
WPL - B1, B16, B24, B36.
JJRC - Q60, Q61, Q62, Q63, Q64 & Q65
Fayee FY Series (with mod's) & Heng Long.
I used 35% Infill & 0.3 Layer with 0.1 layer for the lights.
Use supports (Touching bed) on the models with voids that your printing might not bridge.
Raft or Brim might be wise for the Risers.
Tap the holes if you are not using the original hardware, just self tap otherwise.
