I was wondering why mine seems like it is frozen. I can't seem to move the hinges.

The hinges, especially the horizontal ones, do require a lot of support to print, so there may be some "breaking in" that needs to be done.

Also, you could try sizing-up the print to increase the gaps between the pieces. This was designed around my printer, so the gaps are the absolute minimum. Depending on your print head, speed, heat, and material, the gaps may be too fine.

You could try printing one of these, it has the same hinge,

Magic 8 Ball

I have tried to print quite a few of these and it seems like certain filaments may not work well with something like this. Mine have all ended up snapping without ever breaking free. I'm sure if a different brand of filament is used it would work.

Okay, I designed another version with extra wide gaps between the pieces, so it might work with your printer, http://www.thingiverse.com/thing:1897629

What are the specs of your printer? I'm using the Up Plus2, with .15mm layer height, and ABS (I could never get PLA to feed consistently). The gaps between the pieces is .4mm, so that may be too narrow for your printer (the nozzle could be too large, or your print speed may be too fast, or even too slow). The new version with extra wide gaps has 1mm spacing between the pieces.

Kobayashi Fidget Cube - Fat Hinge - Extra Wide Gaps

This is the first fidget cube design that has held up to actual use (specifically the rounded corner remix). Nice hinge design!

Thank you, glad you like it! They're surprisingly durable. The fat hinge versions are practically indestructible.

With the flat model, I was able to print this without support! It's perfect! I was able to break it free and manipulate it completely. A little clean up helped it out but that's all that was needed. Thanks for the flat version!

This is the only version of a folding or fidget cube that I've been able to print successfully. This is due to the great hinge design. It's also far stronger than other designs. I moves loosely and is easy to manipulate one handed.

Great job!

Could you post a version that is paid out flat with 8 joints facing up? That would prevent the large cubes from sticking together and the least amount of support to clean up later.

The most I could get is 4 joints facing up. Let me know if that helps!

That's exactly what I meant. I was counting each pin as 1. Thanks! It's perfect!
