Thread: Qu-Bit Nano Rand case fit?
There was a thread on MuffWiggler about this issue recently. It's not uncommon-I had the issue when it was in the bottom row of a Doepfer base-case and had to dissemble the module and trim some of the plastic from the button. I bought another Doepfer case and there's more room. You may want to try to contact Qu-Bit, they appear to be helpful.
