Replacement battery cover for Snap Circuits three AA battery compartment. I had two of these break in the same way so I made a replacement model. Fits the same screw. Original has a small plastic washer than just needs to be removed (not needed for replacement cover).

This is the specific set I'm using: https://a.co/d/0isYZeKw

Printed with PLA. Support enabled to help with the screw hole and lid fasteners.
