I messed up — plain and simple.
I 3D printed a skid plate in PLA, even warned not to leave it in a hot car… and then did exactly that. As expected, it melted.
In this video, I show:
The melted PLA skid plate
The new PETG skid plate
Removing the old one
Installing the new one on the Bastard Jr rig
Why PETG should handle heat much better
Lesson learned the hard way — and no, I won’t leave it in a hot car again.
Also… I’m not sold on the name Bastard Jr. (You may not be either)
If you’ve got a better name for this rig, drop it in the comments 👇
