WHERE THIS TEST ENDED
The printed holder breaks during assembly, so I switch to an existing electronics box and keep testing. That solves the enclosure problem for this attempt; the underlying infrared reliability and the cause of the break remain open.

How it was made
The controller pairs a Seeed XIAO board with an infrared transmitter. It sends the projector remote codes captured in the earlier video. The print package was prepared in Creality Print for an Ender-3 V3 SE: one part, no screws, 0.2 mm layers, three walls and no supports. The slicer's estimate was about 31 minutes. Those settings describe the prepared file, not a guarantee that a small clip will survive assembly.
What this attempt established
The fit looked promising, then the print failed. I tried the boxed controller behind the monitor and closer to the projector's receiver. By the end of the clip, placement was still awkward and power commands were inconsistent. The video does not establish why the print broke or prove that the monitor's USB power was the cause of the infrared trouble.
Later follow-up
The September 6–7 build records document a separate fix: the transmitter module had been supplied from 3.3 V and was moved to 5 V. Subsequent desk tests recorded consistent power cycles. That correction belongs after the failed enclosure test shown here.
