Cover plate for GA500 VFD

Having mounted the keypad for the GA500 on the outside of the control cabinet for the CNC Bantam, I'm left with a hole in the cover of the main VFD. This isn't ideal, leaving the control circuitry exposed (albeit within an enclosure) and at the very least looks pretty crap.

But all is not lost. Yaskawa make the CAD models available for all their drives and related accessories, so it's a fairly simply matter of downloading the step file and printing it out:

This I did, directly from the STP file download into the Orca slicer. 

Looks nice, if you can ignore those ripples on the front face.

But there's a catch. That was the first time I've printed a part directly from a downloaded STP file. However, it turns out that it's actually an assembly of 3 components, including 2 covers - one for the USB cable and the other for the RJ45 cable (to the remote operator). 

Trying to remove the 2 covers doesn't end well. I got one off but the other is truly "as one" with the main body.

And when you look at the assembly, it's clear that they actually intersect. Or to put it another way, they are well and truly fused together. Damn. I should have imported them into Fusion to check them first. 

So, simple solution - hide the 2 covers and re-export the cover.

That worked out ok in the end. In another stroke of luck, I found a baby short ethernet cable (25cm or so) that was just perfect for the remote operator.

Final touch - I replaced the phase and ground cables from the VFD to the 16A receptable. They aren't screened but at least they won't burst into flame if subjected to the rated 15A phase current. I probably won't ever do the full 4kW but for low speed high torque conditions (eg tapping?), I may need to generate some high currents. Just visible in the last photo.
