Geometry set with four separate models: a ruler, a 30-60-90 set square, a measuring protractor and a drafting protractor. The set was designed as a practical tactile aid for learning and everyday geometry work, with clear raised markings that can be read by touch as well as by sight.

All markings are in metric scale.

Recommended print settings

• No raft, brim or supports are required.

• Good printer calibration is strongly recommended to preserve dimensional accuracy.

• ABS is recommended for durability, with proper compensation for material shrinkage. PLA is also suitable, but it is less durable.

• For the set square, a 0.25 mm nozzle is recommended.
