I moved house a few times and lost the mounts that come with the Tertial lamps, I really like having them wall-mounted so I drew this version, witha  little more reinforcment thatn a few others I've seen (I printed some and found they cracked when i yanked on the lamp to pull it all the way out quickly)

I added a stop so that the shaft of the lamp doesnt fall all the way in to the holder and won't have as much friction when swinging it around. 

This is printed on my resin printer (Photon Mono SE) in Anycubic Tough resin, with no supports

It should print just fine on a FDM printer, preferably in PETG or ABS, for strength.

The 4 mounting screws should be 5mm or less in diameter, and countersunk.

The cable for the lamp tucks in behind the mount, against the wall.  I will work on an upgraded version that also holds the switch nicely in place, when I get around to it, as it would be really handy to have it mounted flat against the wall.

No issues so far, although I was still dialling in my settings for the resin when I printed these so there is a little warping on the base, it hasn't affected the functionality though
