Rubik's 3x3x3 O-type (2) Square One and Square Two

thingiverse

It's a derivate of my other O-type cube. Now the same angle between all cubies so there are more free positions. Printed in ABS, also PLA should work if carefully sanded. How to assemble: Print the round parts, inside there are holes. Cut rods (I've used M3 threaded rods, 3mm filament should work). Glue together (I've used ABS-juice because of my ABS-print). Fix in a vice until glue is dry. Remove plastic blobs, sandpaper if neccessary. Then I have acetone-vaporized all parts to get smooth surfaces. When dry, Check round parts for assembly: M3-screw -> washer under screw head + a little grease -> one round element -> washer between -> next round element -> nylock nut. If ok, unscrew, fill the tracks with the cubies and assemble again. Paint the sides or sticker it, as you like. If you have problems to glue the round parts: drill from outside and use M3 screws. See red marked area in scad screenshot. Puzzle system meets the square-2 system (outer rows only). Mid row is annother system. edit 2017-03-20 I have added Version (3) and (4). Now there are: Version(1)[thing:1316057] odd angle of the cubies. Only 2 big and 2 small will give 180deg for rotation Version(2) equal angle between all cubies Version(3) [here in zip-folder]: cubies in 30deg and 60deg wide Version(4) [here in zip-folder]: cubies in 60deg and 30deg wide Version 3 and 4 I don't have printed yet. Version 1 and 2 works with no problems so I am sure version 3 and 4 will do.
