Summary

I designed a case for some small Anker items I keep misplacing in my cable/charger/adapter bag. It should protect the items and make them easier to locate. The case has two parts that snap together. It's a tight fit, so I added a tab to help lift the lid off the case.

It holds items from the Anker USB-C to USB 3.0 Female Adapter (2-Pack) and the Anker 2-in-1 USB C to SD/Micro SD Card Reader. Links to the items are below.

STL files are ready to drop into your favorite slicer. No rotations needed. Print with the flat sides on print bed.

Print Settings

Printer:
Prusa Mini
Rafts:
No
Supports:
No
Resolution:
0.20 mm
Infill:
10%
Filament brand:
FLASHFORGE
Filament color:
Burnt Titanium
Filament material:
PLA
Notes:
I used a 0.4 mm nozzle to print. The outside edge of the lid is 0.8 mm, so there could be print issues with a different nozzle size.

Used 2 perimeters, Gyroid fill pattern, and Octagram Spiral for base pattern (for fun). Sliced with PrusaSlicer 2.6.0.

How I Designed This

Designed in AutoCAD (I used both AutoCAD Map3D and AutoCAD for Mac). I started for all of 2 minutes with TinkerCAD, but I realized how challenging it would be to the get the 3D fillets how I wanted. Since I have access to AutoCAD, I used what I know.

I took measurements of the adapters/card reader as well as the original packaging using some cheap calipers I got from Ax-Man Surplus on a trip to Minnesota (my first time using them, so happy with the accuracy). There were a couple of iterations and test prints before I settled on the current model.
