What a tp4056 single 18650 power bank case is
A power bank case for one 18650 cell (18 × 65 mm) with a USB-C TP4056 charger (about 28 × 17 mm) and a small 5 V boost board. The cavity is 90 × 24 × 22 mm with a 9.5 × 3.8 mm USB-C opening, a 13 × 6 mm USB-A opening, a 3 mm charge-LED window and spring contact slots. Walls are 1.6 mm. Print the shell on its side in PETG.
Protected 18650 cells are about 3 mm longer, so the cell pocket needs to grow. Open the ready-made model in SpeakCAD for free, adjust the cell length, then download the STL.
