I got my daughter a Minecraft Light-up Wall Torch for her birthday and found it to be wall-mountable - a bottom corner flips down to reveal holes that can slide onto screws set into the wall to mount it at a 45 degree angle. Pretty cool and clever, but I didn't want to put holes in the wall to mount it so set out to design a mounting plate that could be held to the wall with 3M Command strips so as to not leave any damage that would have to be repaired.

MinecraftTorchMount.stl represents my first attempt, and works well for what it is. You can attach the plate to the wall and it has appropriately sized and spaced studs to mount the torch using its existing holes.

When testing the first plate it seemed to me that placing and removing the torch on the plate and the requisite opening and closing of the corner bit (which simply snaps closed) would eventually cause the hinge to become loose and likely the flap to not stay closed. Since my daughter will likely be putting it on and taking it off a fair bit I decided to go in another direction.

MinecraftTorchMount2.stl is what I ended up with. It's a full mount that the torch simply slips into (up to the first "pixel") without opening the flap. The torch is held snugly in place and can be installed and removed with impunity without damaging it. Much better, in my opinion.

So take your pick... If you're going to be mounting your torch and leaving it alone the original is lower-profile and more true to the game (when you put a torch on the wall in the game it just sticks there, no mount visible). If your kid is actually playing with theirs, they may want to consider the second option.
