Wanted to be able to use standoffs in the rear of my Ichabod Jr as personally I'm not too keen on screwing into the TPU or using a longer screws and adding nuts.
Print in TPU (ideally Sainsmart TPU)
Revision Note: No longer work in progress, previously the holes to wrap around the standoffs were DIA 6mm (incorrectly) so has now been adjusted to suit DIA 5mm standoffs.
Don't want to use standoffs? Print this one instead: https://www.thingiverse.com/thing:3595432
