[This is a first pass at a 1/4"-20 mount for an Ablenet Micro Light switch. It currently is having trouble printing in ABS. I will update when we have good print settings, etc.]

AT Switches are used by people with physical challenges to activate devices, communicate and control their environments. Being able to use standard camera mounts (with a 1/4"-20 bolt attachment) is incredibly helpful for positioning.

This adapter is for the Ablenet Micro Light switch - https://www.ablenetinc.com/micro-light-switch

It adds a 1/4"-20 socket by inserting a T-Nut into a channel. This version requires a .6" tall T-Nut (commonly used to mount things in 1/2" plywood. (At Ace Hardware it is the "Tall" or "Long" version in the bin.)

Here's a video on installing the TNuts: https://www.youtube.com/watch?v=_fH-vgqx3uw&t=8s

[UPDATE: I have added support for both 3- and 4-pronged TNuts at heights of 5/16", 7/16" and 9/16" - note that I've only tested the 9/16" 3-pronged]
