A few years ago, I ran across Ned Batchelder’s instruc­tions for mak­ing a busi­ness card cube.  Since then, I have made dozens of them, includ­ing a few con­joined cubes that form Tetris pieces.  It occurred to me the other day (about a year or two too late to hit the Por­tal craze and at least 6 months too early for the Por­tal 2 craze), that it would be fun to make a Weighted Com­pan­ion Cube ver­sion of the busi­ness card cube.

By print­ing the Busi­ness Card Com­pan­ion Cube PDF file on card­stock and cut­ting on the heavy lines, you will end up with six “busi­ness cards” that look like com­pan­ion cube faces.  You will need either 12 Com­pan­ion Cube faces, or if you hap­pen to have some spare busi­ness cards hang­ing around, you can get away with 6 reg­u­lar busi­ness cards and 6 Com­pan­ion Cube busi­ness cards.  Due to the col­ors of the inner­most layer of busi­ness cards that form the cube, the results look a lit­tle bet­ter if you stick with 12 Com­pan­ion Cube cards.

This is me, half-way through scor­ing and fold­ing each of the “busi­ness card” faces:

Assem­ble the base cube accord­ing to Ned Batchelder’s instruc­tions.  This will use up your first six cards and results in a cube with a bunch of unsightly flaps:

Next, use your remain­ing 6 Com­pan­ion Cube “busi­ness cards” to cover each face.  For each flappy cube face, take one of the facade cube face cards and fold its flaps entirely behind the flappy cube face’s flaps.  This will com­pletely cover up each of the flappy cube faces with a Com­pan­ion Cube image, giv­ing you a fin­ished cube:
