A more minimalistic ‘case’ for these component testers - keeps the battery secure in place & doesn't obscure the test points.

This requires 4x M3 screws and nuts to attach it to the tester.

Please be aware these testers can vary, so be sure yours matches the one pictured. (approx 72x74mm pcb width & height)

The PP3 battery is held in place quite well, mine will not fall out when tipped 90 degrees sideways but it's removable with little resistance.
