If you want the tool holder to be on the right side of the keyboard instead of the left, you can mirror the model along the X or Y axis in the slicer to get that effect. The other foot can be placed on either side so it doesn't matter where you mount it. If you don't want it at all, you can just print two of the small ones.
To mount it, you will have to disassemble your keyboard, since this screws in place of the original. You won't be able to use the original screws that were in the keyboard since this does not use the original raised mounting holes as that would make it infinitely more annoying to print. You will need 2.6x8mm self-tapping screws to mount these.
Yes, you will bend the key switch remover slightly to get it to stay in place. It doesn't bend that much so I don't think you should worry about deforming it. The key cap pulled just snaps into place.
There is a space for Ø8mm rubber feet. The hole is 2.4mm deep. If you want, you can, through the provided Step files, raise or deepen the hole depending on the height of the rubber feet you're using.
I was originally going to only have it work as replacement feet, but when I went to search for the key cap puller to take the keyboard apart I thought “why not add a place to store it under the keyboard”.
The author marked this model as their own original creation.
