iTouchless DZT battery cover replacement

I have an old iTouchless garbage can that we keep in the garage and while it takes some abuse it's held up for a long time. Recently the battery cover broke off and vanished and this model is so old you can't even replace it with OEM.

I made this to hold the batteries but some of the plastic supports seem to have snapped so I used an oscillating tool to just notch out some plastic and drilled a small hole for a screw to hold it. This was my prototype but it fit so well I just drilled the hole thru it rather than model it.

Printed in PLA, 15% infill nothing magical. Flip it 180 and no supports clearly.
