Motorbike garage door opener

This is a garage door opener designed to fit on a 22mm handlebar of a motorbike. It uses a waterproof momentary switch:

and the internals from a cheap replacement garage remote:

This needs to be compatible with your garage door.

The remote is dissembled and the board removed. Wires are then soldered between the external button and one of the buttons on the remote. The board is attached to the bottom section of the print using double sided tape.

The top and bottom halves of the print are pressure fitted together on the bar and zip ties are used to secure it.
