Calculus as never touched before

Calculus as never touched before

We introduce a prototype of a patent-pending geometric-mechanical device for the popularization and the teaching of calculus through hands-on activities.

Materials needed
The proposed device requires 3D printing (we used resin) and laser cutting (of plexiglass and MDF).

For the laser cutting you need:

MDF sheet, thickness 4mm;
extruded plexiglass, thickness 3mm;
extruded plexiglass, thickness 5mm.

Furthermore, you also need:

2 aluminium u-profiles 6x6x1, each one of length 400mm (you can cut them from something like this one)
3 deep groove ball bearings 8x12x3.5 (like these ones)
2 u-grooved ball bearings 4x13x4 (like these ones)
2 o-rings 8.9x2.7 (like these ones)
1 spike rivet (like the long ones here)
1 M3 knurled screw (like one of these ones)
8 countersunk wood screw
