Hi. I am finally getting around to building a true bandaged megaminx based on Meffert's Bi-Cube. All of the necessary gluing has already been finished. The bi-minx has 19 pieces with an edge and corner cubie paired together. That leaves 30-19=11 edges left over. Every face on the bi-minx is permanently bandaged to an edge piece. Since there are one less edge piece than face centers, one edge is bonded to two face centers in the back of the puzzle, immobilizing them. Finally, there is a lone single corner which can interact and move freely within all 10 mobile faces, allowing them to rotate. Just like Meffert's Bi-Cube, a face can only be rotated when the lone corner is present and no other bandaged pieces are blocking rotation.

I believe Andreas Nortmann came up with the idea long before I did:

I made that one around 2003 and it was easier to solve than the bandaged cube from Mefferts.

I will be cutting my own Cubesmith tile material, but in order to do that, I need to make some stencils from a printable sticker template which I don't have. My Ice Minx came with mf8 stickers which I was going to use to make my stencils from, but I seem to have misplaced them them. What I need is a printable template, preferably PDF, from which I can cut a stencil to trace on the back of the tile material to mark for cutting. Help would be appreciated.

EDIT: I found the stickers, so now I can proceed with the project as planned. Thanks for your support :mrgreen:

I can help with that. I just need to know exactly what each face will look like (it's kinda hard to tell from the description) and the exact size of the finished pieces and/or the size you would prefer the tile template to be. If you want I can just try to make a template of what I think it should be.

EDIT: That paper under the orange minx, yes, could you show me that along with actual size dementions? That would be very helpful :)

Hey, thanks for the offer. I just found the mf8 megaminx stickers. I'm not going to make a custom template for each face, but trace the eleven stickers out onto the backing and manually draw the extension lines before cutting each face out. I'll post an update when I have the Megaminx assembled and tiled.

UPDATE: Well, I am pleased to announce after staying up long hours into the night, the project was a success! All ten mobile faces on the bi-minx rotate smoothly. I have pictures, but have not transferred them from my camera yet. It is now 9:10am thursday morning CDT. I need to get some sleep; my brain is :scrambled:

Zzzzzzz.......

Okay, it's been 5 days now. I've just now gotten around to plugging in my camera. I appologize for my lack of more documentation, But basically, here is my workflow:

#1: Color code the megaminx faces.
#2: Peel off outer rim of mf8 megaminx sticker.
#3: Adhere the outline to sturdier backing.
#4: Cut out the support material with Exacto blade to produce a template.
#5: Mask tape the master template to the tile backing.
#6: Outline the shapes in ink.
#7: Remove template.
#8: Manually draw connections for the boundaries of the bandaged pieces.
#9: Cut out the tiles with scissors.
#10: Apply colored centers to appropriate faces.
#11: Insert twin piece into location, one at a time.
#12: Apply appropriate tiles to part match adjacent pieces.
#13: Repeat steps 11-12

For my bi-minx color scheme, I had to choose between the 13 available non-florescent Cubesmith colors and ultimately decided on having a color scheme with similar hues opposite each other, and with one side of the puzzle darker and one side lighter:

Black opposite White
Red opposite Pink
Light Orange opposite Yellow
Green opposite Light Green
Blue opposite Light Blue
Purple opposite Lavender

There you have it :solved:

I believe the puzzle works the best when you try to maintain three-fold rotational symmetry around the free corner. The six faces closest to the free corner (in the shape of a triangle) should all look exactly the same. Face center arms generally point away from the free corner as much as possible in the solved position. You have to twist either 36 digrees right or left for the next set of three faces, preferably in the same direction, then bridge two of the final three faces together, just like the D and B faces of an official Meffert's Bi-cube.

Sorry for the cruddy diagram. I made it in MS-Paint. The fullview is sharper and smaller filesize. Hope this helps you visualize it better. :wink:

P.S. - Kudos to Andreas Nortmann for coming up with the idea years before I did :P
