This file is a copy of the original “Base 1” which is the front left (left when facing your printer), with a pass through slot added. This was done by opening the original base1 and original  base3 (base 3 is the rear base piece with the USB pass-through) step files in fusion360, measuring the original slot in base 3 and adding the same cut to the base 1 part. Then exporting in STEP.

It also includes a plug with a 5mm hole and slot so once you've run a USB cord through the pass-through, you can plug the hole. This is also the original plug step file, modified in fusion 360. This is intended to be printed with TPU so that it can be flexed open to install on the USB cable, then pushed in to the base to plug the hole.

This was modified specifically for use with the BTT Panda Touch display for the P1P and P1S which is typically powered via USB from the available USB port in this same area inside the printer.
