Magnetic 18650 battery holder

I attempted to use this holder - https://www.thingiverse.com/thing:1188235, but it did not actually fit the 18650's, as it was too short. The design was straightforward enough that I simply went to Tinker Cad and created a new file. This requires eight total 2 x 6 mm magnets for closure strength. I used this brand (https://smile.amazon.com/gp/product/B075RZ82HP/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1), but of course, any 2 x 6 mm magnet you prefer will suffice.
