The pictures show a two-color version. Is this available?

Also, could you make a two-color version where half the cubes (in a checkerboard pattern) are one color and the other half another?

I made the two color by stopping the print using a Cura "Pause at height" plugin and swapping filament.

That checkerboard pattern might be enough to finally make me get dual extruders, if there was one.

I just used Cura to program in wait commands at specific levels and then swapped out the filament for that effect. Cura 15 has a plugin called Pause at Height and you tell it what level to pause at, swap filament and the resume your printer.

I've been having problems printing both this and the original one. The bottom and side hinges work perfectly, but the ones that print on the top are always too tight to move properly, even after working them in a bit.

Sometimes hitting them with a hot air gun for a few seconds fixes it, but sometimes that just makes it worse.

Any suggestions?

I'm printing at 0.2mm layers in PLA on a Wanhao i3.

This model has been optimized for a 0.2 mm layer height, and the top hinges move as freely as the rest for me. Let me know what you think if you give it a shot!

The problem with the top hinges is there is nothing to support the bottoms of them, which is why they look rough on one side. So I purposely made them hang lower on the pin to get them closer. I print with a .25mm layer height, maybe using a .2 gets them too close to the pin and they partially fuse? Filament makes a big difference too. Wood PLA works great and the hinges are all smooth flowing, but some plain PLA makes the hinges seem arthritic.

I should have seen this yesterday; I printed one with pins and hinges.....
Maybe later I´ll try this one.

In my opinion, I prefer your version 1, this one had more warping problems with ABS for the first few layers.
I know a cooling fan may help alleviate it, but my Flashforge creator pro is not equipped with it unfortunately.
It did print, but I prefered the quality of the first version.

should i use supports?

If you add supports to a single piece print with internal mechanisms (which this is) then the supports could get in those mechanisms, putting material where you don't want it. So no, no supports.

I didn't and it printed fine.
