I had a need to secure a City Theatrical Showbaby Multiverse (affiliate link) in a traveling set and wanted it more secure than the standard velcro. Counter sunk holes use the 3 factory locations designed for the hanging bracket to mount to the bottom of the transceiver and has 4 holes (2 on each side) sized for a #8 panhead screws for mounting. I printed this face down on a textured bed which gives it a clean finished look using eSun PLA + (affiliate link)
