I didn’t find a mounting bracket for Huanyang HY series to the Altmill similar to the how the official VFD is mounted from Sienci Labs, so I designed one.
This one was designed for Huanyang VFD (HY Series, 1.5kw air-cooled HY01D523B). I don’t know if this will fit other models but thanks to the CAD of the Altmill, it was easy to design one.
I printed with 6 walls, 15% gyroid infill in ABS-GF and got excellent dimensional accuracy. The bracket is design for M5 nuts and I used M5x20 SHCS screws everywhere.
Enjoy!
Note: VFD was temporarily wired with Wago connectors during testing.
