This is a small case for the TP5100 charger module for 1S 2S Li-ion 18650 batteries. The lid is recessed into the case and a few dabs of PVA will keep it in place. The charger has a Red/Blue LED which can be seen if the case material is translucent. White PLA is perfect.
The holes in the side line up perfectly with the wire connectors if the board is attached to a Vero board base.

No supports are required. Be sure to print the lid with the IN/OUT side face down. The lid is secured using a small amount of PVA so it may be removed if required. Sellotape around the case will hold the lid till it dries. I used 5.5mm x 2.1 mm 12v barrel plug leads.
