Component Tester LCR-T4 Case with 18650 battery USB charger and boost converter

thingiverse

I made this case for my LCR-T4 tester because I wanted to make it rechargeable and not use those nasty 9V alkaline batteries that don't last for long. The top compartment of the case accommodates an 18650 battery, a 03962A USB charger and a boost converter. The board that I have seems to be wider than various models you find on ebay so i made the case 8cm wide to be on the safe side. I added a switch as an afterthought on the positive wire of the battery to prevent useless discharge seen that the boost converter is always working. I made the hole with a dremel and used epoxy to secure the thing. In the design there is no hole because if you have different sizes of switches it's better to do it after the print is done.
