After successful ABS prints of a skull with moving jaw and a tv remote bracket (both single colour), I ambitiously thought i'd try this as my first dual colour ABS on my Qidi Xpro, And......... it failed miserably.
Despite an enclosed environment with cooling off, horrific warping on the connectors resulted in the whole cube being solid and the joints failing upon trying to break them free.
I had the bed at 110 and the nozzles at 235. 0.2 layers, 3 walls 20% infill, 3 bottom and top layers, 50mms print speed,
I'm going to try it in PLA next which i'm more confident about. But if anyone has had success with this in abs i'd be grateful for any advise they would care to share.
Thanks Markin for the file, and happy printing all!

you cant put these together

If you mean you can't print the hinges and the cubes separately and then put them together, then you are correct - I have a clear note about that in the description. If that's not what you mean, can you clarify?

i thought you could modify the gcode so it switches extruders half way through so you didnt have to make them seperate

I started to make this but couldn't figure out how to put the 2 parts together.

Is this v1.1 or v1.0? I just printed on Prusa MMU and things are pretty welded together at .15 layer height.

This is v1.1, so it should be "perfect" (no slightly misaligned hinge like v1.0 of the single color cube had). Others have printed this successfully on the MMU, so it certainly CAN work. If parts are stuck together kind of all over the model, that usually points to an over-extrusion problem.

Im trying this out with new 3.1 prusa firmware with linear advance on, i will update with results.

Thanks for this remix, works very well! Fully articulated after a couple of minutes of carefully breaking the joints loose. Used silicone spray to lubricate.

Hah! Nice. This is exactly what I've been meaning to do as probably the first thing I print when we get the multi material upgrade. Had been putting off the modification of the model, but it appears there's no need as someone (you) has already done that. Thanks!

Nice! Now if that multi-material upgrade would just ship we could get this puppy printed!

As soon as it's ready, I'm sure. I'd rather get one that works than one that needs replacement parts not to chew through filament. ;) It's a pity it gets delayed, but I'd really rather have it like this and I like that Prusa are not afraid to make us wait in order not to ship a known faulty product.

Okay, so I started looking into dual extruders... Expensive! And, regardless, there seem to be issues with dual extruders in general. But, it turns out, there's a way to slice the design, and print separately with two colors. Check it out! http://www.thingiverse.com/thing:1944689

Kobayashi Fidget Cube - Dual Color

Yup, there's no question that dual extrusion is challenging. BUT, it still allows for very interesting combinations that can't be accomplished with slicing as you've done. Both methods have pros and cons I think.

Ooh, nice. If you have dual extruders, you should try making the cube, and inverted cube two different colors!

You read my mind! Once I get the hardware, I'm planning to create other variations that allow exactly that. Thanks for the comment, and the great original model!
