I designed a 3D printable protective cover for the Sencor SEC160 calculator.

There are two variants included:

Original version with a notch Version without the notch

The model prints snugly in PLA. If you use other materials (PETG, ABS, etc.), you may need to adjust the scaling. For this purpose, I included a small fit test STL so you can quickly check tolerances before printing the full model.

If you want to modify the design, I’m also sharing the Onshape link with the original CAD model.

Printing recommendations:

Use normal supports, set to grid Choose any bottom surface pattern you like No special settings required otherwise

Thanks for using my model :D
