We have realized that the last set of 4Cube cases we drilled we used the wrong size bit for the USB plug opening, and the cable we provide won’t fit. It’s pretty close, and you could make it fit with a little work with an xacto knife, but of course we don’t expect you to have to do this. If your kit is affected, please contact us and we will send you a replacement cable (provided that we can find one that fits) or a replacement case. Alternatively if you would like to fix or get a replacement cable yourself we can refund you $15. I apologize for any frustration caused by our error.
