5 Layer Pentahedron - triangular prism twisty puzzle

thingiverse

This thing was inspired by MF8 Crazy Pentahedron series. I already did a 3 layer version and this is 5 layer pentahedron. I am uploading 2 versions of parts. One is parts as is, without proper rotation, no supports. You can use your favorite techniques and tools to prepare parts for printing. Most of the parts are bulging and can't be printed as is. I usually split such parts on 2 or 3 pieces that are easier for printing. Then these parts can be glued as into a single part using acethone (for ABS), or dichlorethan (for PLA). So other version of parts I am uploading is prepared in this way. As my previous puzzle I printed this one as stickerless design. I split parts in the way so that I could print subparts with different color. Though you can still print it one color and apply vinyl stickers. I am using 'front face' to refer to 3x5-pieces rectangular face, 'top face' for 6-piece triangle face. Number in the file name reflects how many times you should print the part. Please plan which part should be printed which color. Pieces have 'L' or 'R' suffix that mean left and right subparts, 'T' abd 'B' for top and bottom. I am attaching Solidworks file so that you can see how I made it. Unfortunately it moves not so smooth as it should be. Pieces are often catch each other on movements. Moreover corner pieces appear to be too loose. Yeah, this is design issue. I am open for suggestions how to fix that. Fortunately puzzle is still playable Here is the video demonstrating turning quality https://youtu.be/ohK7KEzRvsE Print Settings Printer Brand: RepRap Printer: Graber i3 Rafts: No Supports: No Resolution: 0.3mm nozzle, 0.2mm layer Infill: 15% Notes: I used ABS plastic for most of the parts, but PLA should work as well. However I strongly recommend printing core in PLA as it has much better layer adhesion (which is critical for core part) Post-Printing Sand parts Sand all corners and edges so that they are smooth. Inner parts should not have any roughness as it may catch other parts. Glue split parts Split parts should be glued. I would use acethone for ABS, or dichlorethan for PLA (remember, dichorethan is very toxic!!! use a good ventilation!) Assembly Center parts have a thin membrane at the hole - this makes printing easier. just drill the hole with 3mm drill. Center pieces are screwed with M3 screws to core. Do not tighten it very much - parts should rotate freely. It is recommended to use special screws for twisty cubes - they have smooth part without a thread at screw head. This will allow smoother rotation and screw will not unscrew. I recommend using springs. Without a spring puzzle will be too loose. Springs should be quite strong. I tried using springs from a pen - my puzzle tend to explode on every turn. Rubick's cube springs should work fine. You may look for springs and screws as spare parts for twisty puzzles (for example these http://www.championscubestore.com/index.php?main_page=product_info&cPath=75&products_id=612) Center caps Once puzzle is assembled it is time to attach caps. Caps are mounted using hooks. Just glue appropriate hooks into caps. Let glue to set before mounting cap on its place.
