A kaleidocycle that prints-in-place! No need to assemble anything; the kaleidocycle comes out of the printer bed ready to use. And no need for supports either.

Enjoy!

Print instructions

The models shown in the photos were printed in PLA. Print at 0.2mm layer resolution or better (the blue one is printed at 0.3mm layer resolution and it doesn't move smoothly). The purple and white are 0.2mm prints and the pink one is a 0.1mm print--the three of them work perfectly well.

I have uploaded two versions of the thing:

• "PrintInPlace_Kaleydocycle.STL" is the standard one,
• "PrintInPlace_Kaleydocycle--tight.STL" where the slack between the moving parts is smaller, and as a consequence it wobbles less and twists better (but there is higher risk of the parts fusing).

The pink kaleidocycle in the photos is the "tight" version. The purple and blue are the standard version and the white is halfway between.
