This is a remix of the wireless Bento Box to accomodate a protrusion found at the underside of my P1S:

The original model did not have a cutout in that area, making it impossible to slide the transmitter box in to sit flat against the printer floor.

An additional change I've made is a PCB stopper integrated to the lid of the transmitter box. I snapped the PCB holder bar on the original model as I pushed in the micro USB power cable. The PCB stopper on the lid helps transfer the load to the transmitter box's case rather than the holder bar without significantly increasing the difficulty of the print.

I created the remix on OnShape, you can find the corresponding project here for further modifications or alternative export methods: https://cad.onshape.com/documents/736e0f2fdbdb8a2d22b979e5/w/4df47443b470f0e38b9f8160/e/147bce5b09f1f145ce20f914
