I needed a case for 312 hearing aid batteries after Costco changed their battery packaging to a totally unusable design. This case holds 8 size 312 batteries with spring loaded friction arms. The screw on cap has a protrusion to push the batteries out of the case. This can be printed in PETG or PLA without supports. Use .15 mm or .2 mm layer thickness maximum to maintain the thread quality.
