Device Details

Overview

This is an inexpensive 3d printed mounting adapter for the original (oval-shaped) AbleNet Jelly Bean switch to attach to camera-type mounts. This adapter was designed by ATMakers.

Usage

The Jelly Bean switch is connected to the mounting adapter using two 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.

Build Instructions

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 (~ 10 g of filament, $0.30)

2 – #3-32 UNC x 3/4″ long Machine screws

 

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.

3D Printing

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 oval 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.

Attaching Mount To Switch

Attach the 3d printed mounting adapter to the back side of the Jelly Bean switch using the two machine screws.
