5 Layer Pentahedron - triangular prism twisty puzzle

thingiverse

This puzzle was inspired by MF8 Crazy Pentahedron series. I've already created a 3-layer version and this one is a 5-layer pentahedron. I'm uploading two versions of the parts: one without proper rotation or supports, which you can prepare for printing using your preferred techniques and tools; another version has the parts split into two or three pieces that are easier to print, then glued together with acethone (for ABS) or dichlorethan (for PLA). Most of the parts are bulging and cannot be printed as is. I usually split such parts into 2 or 3 pieces that are easier to print. Then these parts can be glued together using acethone (for ABS), or dichlorethan (for PLA). So, I'm also uploading a version of the parts prepared in this way. As with my previous puzzle, I printed this one as a stickerless design. I split the parts so that I could print subparts with different colors. However, you can still print it in one color and apply vinyl stickers. I'm using "front face" to refer to the 3x5-pieces rectangular face, and "top face" for the 6-piece triangle face. The number in the file name reflects how many times you should print the part. Please plan which part to print with which color. Pieces have an 'L' or 'R' suffix that means left and right subparts, and a 'T' and 'B' for top and bottom. I've attached a Solidworks file so you can see how I made it. Unfortunately, this puzzle does not move smoothly as it should be. The pieces often catch each other when moving. Moreover, the corner pieces appear to be too loose. Yeah, this is a design issue. I'm open for suggestions on how to fix that. Fortunately, the puzzle is still playable. Here's a video demonstrating the 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 the core in PLA because it has much better layer adhesion (which is critical for the 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 together. I would use acethone for ABS, or dichlorethan for PLA (remember, dichlorethan is very toxic!!! Use good ventilation!). Assembly Center pieces are screwed with M3 screws to the core. Do not tighten them too much - parts should rotate freely. It's recommended to use special screws for twisty cubes - they have a smooth part without a thread at the screw head. This will allow smoother rotation and the screw will not unscrew. I recommend using springs. Without a spring, the puzzle will be too loose. Springs should be quite strong. I tried using springs from a pen - my puzzle tended 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 the puzzle is assembled, it's time to attach caps. Caps are mounted using hooks. Just glue appropriate hooks into caps. Let the glue set before mounting the cap on its place.
