Finally finished out my palette case, but it's not all fitting.

Measured everything and my Error Instruments Radiophonic Workshop module is just under 9 HP according to the calculator.

Any idea how to change the MG listing?

Hey there. Contrats on the palette case.

The module is supposed to be 8 hp but perhaps front panel width varies a bit.

I'm going to measure mine and get back to you.

That's a bummer. I dunno if it's legit supposed to be 8 or 9, but I know I had a Die Antwoord which is supposed to be 13HP, but really wanted 14HP. I was able to get it into 13 HP at the end of the day, but I really had to squeeze it, and I could only get it into my big rack, trying to fit it into a 4MS Pod was a nightmare. For anyone struggling with this or a similar module, I'd say try putting the whole row in very loose around it, then screw down the Error module first then the others around it, and it should work.
