The file 'TARDIS Deluxe – Closed Base With Battery & Switch Slot 3D Printer Model' is (step,stl) file type, size is 20.7KB.
I have designed a closed base for the TARDIS by countspatula (https://www.thingiverse.com/thing:124033)
I have also attached the step-file that you can redesign it for your components. I used a double AAA battery-slot: https://www.reichelt.de/batteriehalter-fuer-2-microzellen-aaa-loetfahnen-halter-2xum4-nlf-p57125.html
and for the switch a NINIGI S22L https://www.tme.eu/de/details/s22l/schiebeschalter/ninigi/
Have fun
