About this 3D model

Update After some feedback about the issues with the single wall for the hex nut, I've decided to add more structure to this area. Several walls will now print in this area. 18650 Battery holder and tester for protected and unprotected cells. Slotted, brass, #6-32 screws were flattened with a rotary tool for better cell contact. Note that the hex nuts were designed to be a press fit, these may be difficult to press in with just your fingers. Printed with 3 walls. Materials: Brass #6-32, 1" screw Brass #6-32 nuts
