This is a frame for the iFixit Electronics Essentials toolkit. I printed it in Bambu Lab PLA Basic and I'm pleased with the results.
You will need 4 M3x16mm and 4 M3x12mm screws for assembly. I used socket cap screws.
The author remixed this model.
The original was made for the Manta toolkit. I resized it and modified the sides for ease of opening.
