D&D - 75mm (Huge) LED Base (link to battery holder in describtion)
thingiverse
I designed this for my DnD miniatures because i wanted to integrate LED light. I thought of a way to but the button cells in there as well as all the wiring. I use hot glue to put these in: https://www.amazon.de/gp/product/B0823W1MX7/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 For two CR2023 button cells you will need 150ohm resistance for a 3V LED. The size of the battery holder is roughly 23,7mm x 52,2mm without the switch and the wires sticking out, so they wont fit perfectly underneath a 50mm (large) monster-base.
