Easily customizable remote holder. You only need to change 6 parameter to fit your remote:
height: the length of your remote, minus maybe 10-20mm to leave part of the remote to pull out
length: the width of your remote
width_open_end: how thick your remote is
width_closed_end: normally you don't need to change this. It's set to create a 6mm slope so your remote can fall in easier and stay there
wall_thickness: if your nozzle is 0.4mm then 2 layer = 0.8mm would be perfect. If your nozzle is 0.6 or above then set it to that as only 1 layer is sufficient
bottom_curve: most remote have curved bottom. this is where you can set how curved it is
Print it in its original orientation: open end up top. Will take around 1 hour, but obviously differ based on how big your remote is.
Afterward, use a double sided tape to secure it. I've used them for over a year and can testify that normal double sided tape have enough strength to hold all our remotes.
