I have these LoraTap Outlet plugs for my house, however, it only comes with one base plate that lets you mount it to a wall. The baseplate is for this specific model here:

LoraTap Mini Remote Control Outlet Plug Adapter with Remote

Designed and printed additional mounts so I could take the remote with me into different areas and still have a place to mount them.

Design uses 12x3 circular magnets that are press fitted. I also added a slot to add a 3M command strip if you're not mounting this base to something metal.
