Description

This is an exactly proportional copy of the companion cube from portal, as traced from a screenshot.

There were a few cubes already on thingiverse which I've printed out dozens of, but they all had some issues with printability or proportionality. I think I've solved all the problems with this version.

This version is flat bottomed, and has no significant overhangs over 45 degrees.

It is carefully designed in Solidworks so any changes can be quickly and easily made. I also included step files since Solidworks is pretty unfriendly to a lot of other programs.

The default size is exactly 1in^3

The Cube in the thumbnail was printed by a Fablicator.

This printed great for me! Thanks for the great model.

I printed this at-original-scale (1 inch x 1 inch) on our Makerbot Replicator 2 the other day, on the following settings:
- "High", No rafts, No supports

It took a little over ~1 hour. I'd be interested in reprinting at a larger scale, e.g. 2 inches x 2 inches. Though I do like this tiny 1 inch x 1 inch cube on my desk!

Note: This does have a flat bottom, so I suppose it's not a /perfect/ replica of the Companion Cube. However, since this eases printing /considerably/, I'm still very happy with it! No need to spend time removing supports/rafts.

Anyone using Slic3r having problems with the top looking good? I know I am? Any advice?

Ditto. Top is rough on both of them I've printed. Now sure why. I have Slic3r set to print two top layers in Perimeters.

i will have to try this one.. printed the other ones without a flat bottom and the support material ruined one side of the cube.. waste of 15 hours.. (scaled 300%)

This is an extremely impressive print. was any sanding or smoothing involved, or did it come out of the 'Fablicator' just like that? Also, where could I buy one? They don't seem to be selling a thing on the website :(

Nice model! .. Except you forgot the lines.. There's supposed to be four lines on every side pointing out from the heart in the middle. I really want to print this model, it looks really nice.. But maybe you can add the lines to make it accurate? :)

Wow, that's an impressive print quality! I'm curious what's the layer height and speed you're using?

1. This model scales pretty well to 2"^3 (not too much layer separation with ABS, if hood
&
amp;windows are used).

2. I printed some of these for my girls, and they carry them around everywhere (and they've not even been exposed to Portal, yet (I need to fix this and introduce them).

Thanks for sharing such an amazing model with us!

Fantastic print. Would love to know where you got that plastic. Also, would love to try out a Fablicator some day :)

In the interest of protecting the innocent, I'm not going to tell people where I got the plastic from. They have a 50% success ratio of delivering plastic within spec, and the rest just causes headaches.

Upon further analysis from my previous comments,I'm 99% sure it is high impact polystyrene (very similar to ABS).

I get the same good results with pretty much any plastic with a consistent diameter, though.

This would be awesome with hidden motorized wheels and an hidden sound module. Who said the companion cube could not speak?

I hope you don't also try adding something that threaten to stab you... or that does...

What did you use to clean up your cube after it was done printing?

There was no clean up. Came out of the printer exactly like that.

Very nice job! Kudos for posting your design files and taking care while creating them.

The print looks awesome, too! Is that PLA or ABS?

It's supposedly PLA, but behaves more similarly to ABS. My guess is PLABS of some sort. Strangest material I have worked with so far, courtesy of china.
