Device Details

Overview

This is an inexpensive 3d printed mounting adapter for connecting a commercially available LITTLE Candy Corn Proximity switch to camera-type mounts. This adapter was designed by ATMakers.

Usage

The Little Candy Corn switch is screwed onto the mounting adapter. 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)

3 – #xx? flat head wood 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 should be printed with the flat, rounded triangular portion down. Support is required for the tee nut mounting hole.

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

Rotate the rear portion of the LITTLE Candy Corn switch to expose the three mounting holes. Align the lobes to the mounting adapter to ensure that the power switch is accessible and then use the three flat head wood screws to connect the switch to the mount adapter. The switch can then be rotated into its normal position.
