Triple LR44 (SR44 AG13) battery replacement (eliminator)

Replaces batteries in cheap toys and devices with an external power source. Use 0.7-1mm thick wire to create the contacts. Devices with leds might need an internal resistor, which matches the internal resistance of the cells. 90-150 should do just fine.

I printed it in  ASA, 0.15mm. Printed with supports and the cutout facing upwards. I stripped about 5cm of thick cat8 wire for the contact. I added a series resistance on one wire and hid it in its compartment. I then filled both compartments with HMA.
