Modular AA Battery Holder

Hello! This is my first project for MakerWorld, please let me know if you need any tweaks. I made modular storage solution for AA batteries. The system consists of three interlocking sections:11xAA module - 65x85x35 mm8xAA module - 50x85x35 mm4xAA module - 30x85x35 mmThe pieces snap together side-by-side, allowing you to build custom-capacity holders that match your exact needs. Printing:No support needed, used generic PLA profile.I like to use rectilinear filling and several skirt loops, but you can always use standart settings, there should be no difference. First connection may be very tight. If stuck, gently rock the parts side to side while pulling apart. After a few uses the lock loosens up and snapping becomes easy. Boost Me
