I wanted to fit larger cells into my Radiomaster Boxer, but the 21700 batteries with holders didn’t fit. So I designed a flat, minimalist version that’s super easy to print. The tension is provided by TPU, and I included different hole sizes (1, 2, 3 & 4 mm) depending on what kind of contact surface you have at home. I used 3 mm copper contacts, but thumbtacks will probably work just as well.
