Four chess coasters, each with a real "White to play, mate in 2" problem. Solve it while your tea cools, then turn the coaster over: the full solution is engraved underneath. Printed in 4 colours, flush and perfectly flat so the cup never wobbles, and stored in a castle rook.
The problems are real
Every position was found and proved by brute force with the python-chess library: mate in exactly 2 (no mate in 1), one single winning first move, and that key move is quiet (no check, no capture), which is what makes a problem pretty.
Coaster 1 is a gem: the key is a quiet king move, and Black can promote a pawn to queen, rook, bishop or knight; each one gets a different mate.
Board in the classic diagram layout: a1 dark, knights facing left, coordinates on the frame.
Colours (AMS / AMS lite, 4 slots)
Green: base, frame and dark squares. Cream: light squares. White: white pieces + outline of the black ones. Black: black pieces + outline of the white ones, so every piece reads on any square.
The colours are only the top 0.8 mm; everything is flush. The four bodies were checked to touch without overlapping (0 mm³).
Ready-made 3MF files for the A1 mini with the 4 colours already assigned: 1 h 11 min to 1 h 16 min and about 31 g each (without purge waste; the prime tower is off). The 3MF files also open in OrcaSlicer and PrusaSlicer with the 4 parts separated. The OpenSCAD source and the puzzle finder (find_mate_in_2.py) are included, so you can generate new puzzles and coasters.
Rook holder
A castle rook with crenellations and a pointed-arch door that holds the four coasters (101.6 mm inside, 0.8 mm clearance), with the top problem on show. 1 h 21 min, 55 g, no supports.
About this design
Designed with AI assistance; the chess was checked by software, the geometry in code, and the multicolour 3MF was sliced in Bambu Studio. Pictures are 3D renders, not photos. Not printed yet: makes and feedback are very welcome.
