Fisher Price Construx Stair Set (compatible part)

History:
Construx is a brand of plastic building toys introduced by Fisher-Price in 1983. Construx feature beam-like pieces of varying lengths that snapped on to cubical connector knots in order to build large shapes. These are relatively secure even though no nuts or bolts were used. Panels allowed assembly of flat surfaces. Hinges, motors, wheels, and other movable parts expand the number of different shapes that can be built, and make moving creations possible. Construx was discontinued in 1988, briefly revived by Mattel in 1997, and then discontinued again.

When trying to build / re-create a vintage Fisher Price CONSTRUX Playset (Lunar Command Station) with my kid, we noticed that there was actually a stair set.
So I created a compatible stair set, which is WAY easier to 3D print then the original part.

These were printed from PLA+ for proto and PETG for real with supports being needed for the arches. Best to print in 25% infill.

Print Profile:
0.2mm layer, 3 walls, 25% infill

Enjoy!
