    ## Camera Mount Adapter for 50mm PikoButton

    Overview

    This is an adapter for connecting a medium (50 mm) PikoButton (https://www.pikobutton.com/) to camera-type mounts. This adapter is based on the style of similar mounting adapters by ATMakers.org. Specific 4mm to 1/2″-20 UNC thread adapters are available, but they can be difficult to source or expensive to ship. This adapter is an inexpensive alternative.

    Usage

    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

    Bill of Materials

    To assemble the mount with the switch, you will need:
    1 – 3D Printed Mounting Adapter (~ 5.2 g of filament, $0.26)
    2 – M4 machine screws, 12 mm long ( $0.50-$1.00)
    1 – 1/4″-20 UNC tee nut, 5/16″ long ($0.30 e.g. https://www.mcmaster.com/90975A025, also available at hardware store)

    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

    Design

    The 50 mm Pikobutton has three threaded M4 mounting holes on the back. One hole is in the center and the other two are spaced apart by 31.5 mm. The two spaced holes are about 6 mm deep.

    The adapter was created using Autodesk Fusion 360.

    3D Printing

    The mounting adapter is designed to be printed with the narrow end up, with support.

    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 mount to the PikoButton using the two M4 x 12 mm machine screws.
