A four piece coordinate motion puzzle that assembles into a truncated octahedron. This is a copy of a beautiful wood puzzle of mine (see photo). The wood puzzle was made in 2004 by Interlocking Puzzles. The designer is listed as Steve…
Four pieces assemble into a tetrahedron. This puzzle is not difficult but you may be confused if you are used to cube puzzles! This puzzle was invented by Wayne Daniel. Print two copies of each piece. The pieces do not require supports if…
Print three copies of the basic piece, and three copies of its mirror image (I recommend using a different color). No supports are needed, there is a 2 cm bridge at 2 mm height. [To mirror a piece in PrusaSlicer, simply select it and then…
A puzzle designed by Stewart Coffin in 1996. Three pieces, all different. Print one copy of each bunny. Assembles by coordinate motion. This puzzle was Jerry Slocum's IPP17 exchange puzzle. All Bunnies can be printed without supports! The…
I printed a copy of Oskar Van Deventer's “Screw Burr” and had an idea for this variation. This is not a difficult puzzle, but precise alignment is needed to assemble the pieces. If it is not going together smoothly most likely some piece…
This is a dissection of an octahedron into six identical pieces. Assembly is surprisingly easy, given that it is coordinate motion. The puzzle does not interlock very well, which helps. The octahedron has an edge length of 6 cm. If you…
This is Stewart Coffins design #94. Print two copies of each piece. The pieces need supports “everywhere”. To stop Slicer from putting in too many supports, I set “Overhang threshold” to 30 degrees. You only need supports for the…
Four (identical) pieces assemble into an “OctaBall”, my name for an Octahedron intersected with a sphere. Assembly is surprisingly difficult. The pieces have no symmetry and appear warped or tilted (your printer is not messing up). It is…
Six pieces, all different, assemble into the second stellation of the regular dodecahedron, also known as the “Great Dodecahedron” . David Bruce invented the original version in 1997. His version is the wood puzzle shown in the photos…
This is Stewart Coffin's design #42. In wood it is normally made from seven wood types. Here you can make it in one, three or seven colors. You need to make six copies of the basic piece, piece variations are only in the color. There are…
Six pieces assemble into a flat star shape which doubles as a trivet. I increased the size from the original wood version (made by Black Dog Puzzles ). The trivet is about 7" or 18 cm across, and 1/2" or 1 cm thick. If you intend to use…
This six piece burr assembles into the first stellation of the regular dodecahedron. This is a variation I found when exploring David Bruce's version. Assembly is not too difficult, one move requires easy coordinate motion. All pieces are…
A difficult packing puzzle and a demonstration of the Pythagorean Theorem. Pack all the pieces in the two smaller boxes, or pack all the pieces into the large box. The pieces are all different and resemble tiny beds. The volume of the…
Four pieces assemble into an “OctaBall”, my name for an Octahedron intersected with a sphere. Assembly is surprisingly difficult. The pieces have no symmetry and appear warped or tilted. It is remarkable that they can assemble into a…
This is a set of 12 Pentominoes with a case for storage. The Pentominoes are made from cubes, a more proper name would be planar pentacubes. The case is 5x4x3, there are 3940 ways to pack them in that case. But good luck finding even one!…
Six pieces, all different, can be assembled into an octahedron. This puzzle was invented many years ago by Rik Brouwer, who has approved its appearance here. Rik made several in wood and more were manufactured and sold. I include the…
A puzzle invented by Stewart Coffin. Ten pieces form the basic alphabet. Six pieces can be assembled into a rhombic dodecahedron. Print ABCDEF, these six pieces form the classic Stewart Coffin puzzle: Garnet (#1). ACDEFG make Garnet #2…
This is a variant of Stewart Coffin's Hexsticks puzzle (#25-A). It is #269 in his numbering sequence. There are 12 pieces total and 4 types of pieces. Print 7 copies of the Standard piece, 3 copies of the Skinny piece, and 1 copy of the…
This is Stewart Coffin's puzzle "Overdrive", the most difficult in his series of "gear puzzles". It is STC design #117. WARNING: This puzzle is difficult to assemble! Fortunately, it has a second solution which is easier to assemble. I…
This is Stewart Coffin's design #63. It appears to be a standard Diagonal Burr , but looks are deceiving. The pieces are easy to print, no supports needed. Six identical pieces, I printed two of each color. Assembly is a bit tricky.…
Twelve identical pieces can be assembled into a 6 cm cube. This puzzle appears (virtually) on the cover of Cubism For Fun, Issue #117, March 2022. Thanks to Bruce Patterson who designed this puzzle for giving me permission to post it…
This is a 7-piece burr with very unusual pieces. Unlike most burrs, the hard part is figuring out the assembled form. I don't include a photo of the assembled puzzle, as it is a spoiler. The assembled puzzle interlocks nicely and will not…
A simple three piece burr with four different assemblies. In the symmetric assembly, it looks like a common Diagonal Burr , but internally is quite different. Place it on your coffee table in its "broken state" (first photo) and see if…
A six piece puzzle with removable maze plates. The puzzle can be assembled in one step with maze plates removed. Maze plates are then added and secured with a screw. A good first maze is the Sequential Star Maze (included). This turns the…
Build symmetrical pyramids using these seven pieces. Given that they are composed of spheres joined together, this task is difficult. WARNING: This puzzle will severely test your 3D visualization of spheres. Print one copy of the piece:…
Nova Plexus is a puzzle invented by Geoff Wyvill and made in metal by https://twobrassmonkeys.com/ The puzzle is made from 12 identical rods and when assembled is self-supporting, amazing but delicate! Many shapes will fit neatly inside…
This 5x4x3 box has a 7-hole opening on the largest face. I discovered that this opening has a unique solution for packing the 12 pentominoes, without rotations. Print one copy of the pieces. The pieces are the same size as used in the…
The Bakos Compound is is a polyhedron compound of four cubes with octahedral symmetry. It can be printed as a 4-color print, but this would take over 40 hours on a Bambu X1C. Instead, I print each color separately. Color 1 (black, in the…
Four pieces assemble into a regular dodecahedron. There are two solutions. One is easy to assemble, the other is tricky. The tricky solution has some very unusual movements. Try to find both solutions. Print two copies of each piece. No…
This 7-piece puzzle assembles into a cube-octahedron dual solid. I borrowed the original wood version from the collection of Stan Issacs. We do not know the original designer or maker. Please contact me if you know who designed or made…
This four-piece puzzle was crafted in wood by Wayne Daniel around 25 years ago. I have reproduced the puzzle using 3D printing. The puzzle consists of two copies of each piece, I modeled it using BurrTools. You can print the pieces in a…
Internally, this is a common Diagonal Burr (aka Star Burr). Like the Diagonal Burr, there are six identical pieces. But while a Diagonal Burr assembles into a stellation of the rhombic dodecahedron, these pieces assemble into a Stella…
This puzzle is from the classic book "Puzzles Old and New" by Jerry Slocum and Jack Botermans. There are 5 pieces made from 14 spheres. One can pack the box with all 5 pieces, or with only 4 pieces. In the second case the box still…
I use these to make ball puzzles with wood balls. I include models for ¾" = 19 mm diameter and 1" diameter balls. I include the OpenSCAD program so you can make a part to fit any size ball. In the past, I used an SLS printing service to…
This is a stand for your Hedgehog , a fantastic wood puzzle by Kagen Sound. The stand has a diameter of 5 inches and the puzzle nests perfectly into it. It will keep your valuable Hedgehog from rolling off a table. There are actually two…
