A fascinating 3-d project, with a complex interior and moving parts, all in a single print.
Push the ball past the spring-loaded jaws, it's only about eight correct moves to get it out, can you discover the secret?
What about your patience - maybe you'll smash the cube to recover the ball!


It is designed for 10mm or 3/8" balls, the holes are nominally 11.5mm and the viewing holes 7mm. Balls down to 8mm or 5/16" will work.
The correct orientation for printing is with the bigger entry/exit hole on top. After printing, clean out the hairs and imperfections with a sharp screwdriver.
I used PLA, if you want to change the scale or material, print the small test model to check the jaws and hole size.

It's actually quite easy, the maze could be much more difficult. To practice, put the ball in the exit hole and learn in small stages.

If you really have to cheat, study the inverted holes model. Or watch the video, http://youtu.be/AvnNPD1WQfs

May I have the ball size?

Do you print with infill?

RichMac - in reply to shh

I printed it with almost no infill, I was surprised the top of the cube printed. My trouble was that I was entering 0.3 instead of 30 for the % of infil! . But it still printed ok.

The video attached to this Thing is private, I can’t view it!

Thanks for pointing that out, Google has integrated the Youtube videos with Google +, and changed everything. Should be OK now.

Works for me now, thanks!

Printed in just under six hours for me at 0.2 layer thickness and 30% infill.

Excellent, I hope I can get it to print :)

I noticed there is a 90° overhang on the inside of the jaws. It could be changed to 60 or 45 with no problems I think.

What did you design this with?

Small problem with the overhang fixed. I put a slight peaked roof on the main holes, it all seems to print well. I used 0.27 layer thickness and 30% fill.

Well spotted, the jaws do have an unnecessary overhang, it printed OK. I'll fix it tomorrow.

I use Solidworks.
