Camera Mount Adapter for Big Switches
Setup & instructions
This is an inexpensive 3D printed mounting adapter to attach larger commercial assistive switches to camera-type mounts. The adapter was designed by ATMakers. This adapter should work with the following AbleNet switches:
- Big Red®
- Big Beamer®
- BIG Step-by-Step™
- BIG Step-by-Step with Levels
- BIG Step-by-Step Choice with Levels
- BIG Step-by-Step GamePlay
The switch is connected to the mounting adapter using three screws. The mounting adapter can then be attached to a tripod or a mounting arm with a camera connection (i.e., 1/4″-20 UNC) to provide convenient switch placement.
A comprehensive set of instructions for creating this style of switch mounting adapter is available at the following link: http://atmakers.org/2017/02/at-switch-adapters/
Bill of Materials
To assemble the mount with the switch, you will need:
1 – 1/4″-20 UNC tee nut, 5/16″ , 7/16″, or 9/16″ long (~$0.30, hardware store or McMaster-Carr)
1 – 3D Printed Mounting Adapter, design file to match length of tee nut (~ 70 g of filament, $2.10)
3 – #10-32 UNC x 3/4″ long machine screws
3 – #10-32 UNC Nuts (for switches with holes)
You will also need the following temporarily to install the tee nut:
1 – 1/4″ Washer
1 – 1/4-20 UNC machine screw or bolt, 3/4″ – 1-1/2″ length
1- Screwdriver, drill or wrench (depending on the type of bolt chosen) to tighten the bolt.
The mounting adapter is designed to be printed with support. The print should be oriented so that the cylindrical portion of the tee nut is vertical, with the large flat surface on the print bed.
Assembling the Mounting Adapter
Clean out any support material from the center section.
To install the tee nut, line up the barbs of the tee nut with the slots on the mount adapter. Put the washer on the 1/4″-20 UNC bolt, and thread it through the adapter and into the tee nut. Tighten the bolt until the tee is flush with the bottom of the adapter. You can then unscrew and remove the bolt and washer.
