Can you solve Trisometric? 
Trisometric is a traditional style packing puzzle that comes in 3 difficulty editions. The design is entirely based around the equilateral triangle. Shapes fit so well together in so many ways, but there is only one true position for each piece relative to another piece. 
All the pieces have a nice tactile feel and have interesting geometries.
I initially designed the original puzzle but thought it might be too hard so have created two easier editions. Each edition has certain clues making it relatively easy to know that certain pieces will never go in certain positions in the tray, which makes the puzzle easier to start off with,  this is particularly relevant for the Expert and Medium editions.

Easy Edition:         15 Pieces  -  Ideal for a casual challenge, or perhaps younger folks, come on, I know you can do it.

Medium Edition:  24 Pieces  -  A decent challenge for all that can be frustrating yet highly satisfying. 

Expert Edition:     54 Pieces  -  Brutal and punishing, only the strongest will survive. Attain Enlightenment!

 

PLEASE NOTE: These puzzles are not designed for very young kids, and have some small or sharp pieces that could be a choking hazard.
 

PLEASE NOTE: I have not created a version of this that is suitable for the A1 Mini, the reason is the spaces I need to give each piece in the scrambled positions are quite tricky to pack into as small a space as possible. It is possible to print the puzzle assembled (in place)  however I have only tested this with the original Expert version and found that some of the corners might stick, and I have not tested assembled / in-place print for the Medium and Easy editions. I have provided all the .stl files so you can try to pack the pieces in to a small enough space for the A1 Mini.  I would not recommend scaling the puzzle due to issues with allowance gaps for the trays.

PLEASE NOTE: I have  uploaded the Medium difficulty edition as the default download, you can find the Easy and Expert editions in the additional download files.

PLEASE NOTE: I had a lot of trouble trying to make a tray that worked for all the 3 editions. I think because of the sum of all the allowance gaps between the pieces across the 3 editions, and because pieces where different shapes I had to make ever so slight adjustments to each tray for each edition to ensure pieces where not getting stiff to place in, or in some cases impossible to fit in. So please make sure you print the right tray for the right difficulty edition of the puzzle.

PLEASE NOTE: Remember you can always choose your own colors, and as with all my puzzles that include a tray, ideally the puzzle is best if you print the tray in a different color the pieces,  or if you prefer the same color for both.
Please let me know if there are any problems with this as so I can try make additional modifications to it.
