lead acid battery holder 12V 1,2Ah

a little shelflike holder for one of those sealed lead-acid hobby batteries, the small one of 1,2 Ah. battery fits loosely. The weird hole in the back wall is room for a metal angle bracket in case you don't trust the plastic to hold the weight over time.
Inner dimensions are 98mm X 44mm (wall thicknesses: 2mm), overall height: 42mm (not ass tall as the battery that fits in it).

This kind of battery:
