This is a holder for the RC Tank target sold by LegoDEI on Etsy:
https://www.etsy.com/listing/887629159/modular-ir-target

This is a simple stand to hold it upright, and leaves room for the connectors on the back.

The holes are sized for #1 screws, and you should also put a nylon washer under the screws to prevent stressing the board or shorting anything on it.

I printed it on Form3 with Tough2000 Resin. The holes fit a #1 screw reasonably tightly, but this could vary a lot depending on printer. According to tap/die chart, a #53 jobber drill bit should be appropriate to prepare the hole for a #1 screw, if it comes out too tight.
