This 3D model is a foldable and detachable ring board created for activities based on the ENFEN Test in educational and training contexts (teachers, psychology / neuropsychology / education students, etc.).

The model consists of:

Two main bases that connect to form the board.

Three cylindrical towers where the rings are placed during the task.

Colored rings (yellow, green, white, blue, red, black) that can be used for classification, planning and spatial organization exercises inspired by the original test material.

The main goal of this design is to provide a compact and portable version:

when not in use, all parts can be disassembled, packed into the base and stored in a box, making it very easy to carry between classrooms, offices or training sessions.

Important note:

This model is inspired by the ENFEN Test and intended for educational, training and support use. It does not replace the official test materials and should not be considered a certified version of the test.

Print Recommendations

Recommended material: PETG (for higher strength and durability).

Layer height: 0.2 mm.

Nozzle size: 0.4 mm.

Infill: 15 % recommended.

Wall/perimeter count: at least 3 perimeters to increase strength, especially for the towers and rings.

Tolerances: make sure to check your printer’s dimensional accuracy.

In my case, a -0.1 mm horizontal expansion (or similar compensation) was needed so that all pieces fit perfectly (rings, towers and base).

Supports: usually not required if parts are oriented correctly, but this may depend on your printer.
