The Radio Cube 3 is a cubic transformation of Jason Smith's Radiolarian 3. It has icosahedral cut geometry, and it is slightly shallower-cut than my DeFTI (aka "Eitan's Star" soon to be released by MF8). To build this puzzle, you will need 20 flat-head M3 screws that are at least 12mm long (or the standard equivalent). You can buy stickers at Oliver's sticker shop: http://speedcubing.hu/webshop/index.php?main_page=product_info&cPath=6_41&products_id=386

The Master Helicopter Cube is an edge-turning cube with two layers on each turning axis. This is a flat-cut version of the puzzle I presented back in August 2010, and I have redesigned the mechanism several times since then. This mechanism is very stable, and rarely locks up. To order this puzzle, add it to your cart, check out, and then email me your Order Number. (eitanspuzzleshop@gmail.com) Be sure to specify that you got the "Master Helicopter Cube". You can order the stickers from Oliver Nagy here: http://speedcubing.hu/webshop/index.php?main_page=product_info&cPath=6_41&products_id=334&zenid=88f5f2cbc17170175a2873bf982812b0 You will need twelve 4-40 5/8" or M3 16mm flat-head screws.

The MegaTwist is a twisted transformation of a Megaminx. It solves just the same as the original puzzle, but with the added challenge of the shape-shifting. For more information and pictures, see the Twisty Puzzles forum. http://twistypuzzles.com/forum/viewtopic.php?f=15&t=22187

This is my entry into the TwistyPuzzles.com puzzle competition. It is a transformation of a 2x2 that fits into a shell only when it is solved.

If you order one of these puzzles, please send me a message through either YouTube or Shapeways, and I will send you instructions on how to assemble it. You need a regular Eastsheen 2x2 and superglue.

PLEASE READ ENTIRE DESCRIPTION.  THIS FILE IS NOT A COMPLETE PUZZLE!

This is the Non-Stickerable (Dyeable) version of the Compound Cubes.  The puzzle is in the shape of M.C. Escher's compound of 3 cubes.  See the video below for more information.

This file prints some of the parts needed to make the NON-STICKERABLE (i.e. Dyable) Compound Cubes.  To make a full puzzle, you need to print:

One copy of this file
Three copies of the PART 2 OF 3 file
One copy of the CORE file

This is only a DIY kit.  You will need to provide your own screws (#4-40 at least 1/2'' long).

The full puzzle will cost $180 in WSF.  (Once Shapeways begins offereing more Dyed Strong & Flexible colors, you will be able to order the puzzle in multiple colors.)

This is the core to the Compound Cubes.  You need this to make either the Stickerable or Non-Stickerable version of the Compound Cubes.

Twisted Cube - Type 1

The Twisted Cubes are a shape-modification of a 3x3 Rubik's Cube.  This makes them a bit more interesting to solve, and much cooler-looking when scrambled.  Now you can get your very own DIY version of the Twisted Cube Type 1.  This one looks like a 3x3 on top.

Save $10 by ordering both together!

To order, buy this file from my Shapeways shop, and then be sure to send an email to eitanspuzzleshop @ gmail . com (remove the spaces) with your order number and which type you ordered, since I have to intervene and send them the correct files.
You can get stickers for $6.70 from Dr. Sticker.  Just email him at dr-sticker @ gmail . com (remove the spaces) and tell him what colors you want on which faces.  Be sure to tell him that you want type 1 stickers!
The puzzle needs 6 M3 screws at least 10mm long.
