Hey team,
A really quick model to fix a slight issue with a transformer we recently picked up on ebay. These transformers go by many ‘brands’ but they all appear to be quite similar, so there is a good chance these replacement feet / bumper will fit.
The primary issue with the original rubber feet is that they leave black marks on kitchen benches and tables. We tend to use these transformers for cooking into two locations, so we are often moving the transformer and it didn't take long for us to notice all the black marks appearing.
I've modeled the feet more or less identical except adding the addition of a chamfer internally to match the original screws. I suspect the manufacturer just bought a large number of generic feet, which are probably more suited to bolts and a washer, but this transformer instead just uses what looks like a wood screw going into sheet metal.
I printed these in Australian Made Aurarum TPU with an 80% infill using the gyroid pattern for some additional strength under compression in blue.
The new feet / bumpers are a good improvement and happy with how they turned out.
Hopefully this is useful for somebody out there.
Cheers
