I had a Hoffman enclosure that i needed to use for a project, but there was no backplate. So, I made one! This fits on a single buildplate for prusa MK3 or MK4 printers. It has holes that should accommodate M3 bolts, or other screws.
It's certainly not as nice as the factory backplate, but when you're in a pinch, you have to improvise.
The author marked this model as their own original creation.
