Split bolt splice cover

Split bolt insulating cover for splicing 6AWG and similar large diameter wire. This will accommodate split bolts up to 29mm long. Ideally should be printed with ABS or Nylon for higher temp rating, but a proper connection shouldn't heat up thus PLA may suffice. Naturally this is not a UL rated item, use at your own risk.

Second version is a bit more narrow than the first one.
