Try to assemble the 4 pieces into the shape of a latin letter T. Most people find it surprisingly challenging!

This is an adaptation of a traditional puzzle.

I recently built the Ninja CNC kit from CNCSNAP.com. They include some pretty good harware but I wanted my machine to be able to cut heavier material. So i began making upgrades to the machine. I replaced the laser cut motor mounts with HEAVY DUTY 3D printed ones that are probably a little "over" built. But stronger is better right? I also designed a very robust tool holder that fits the motor they supply with the kit. I love this tool holder, it works great. Note: you will need to drill a hole in the end of the clamp to bolt it together. I recommend a small diameter machine screw. Next I stiffened up the guide rods with a set of support claps on each rod. I made them slightly under sized so you will need to run a 1/4" drill through them. My "Y" axis coupler broke so I replaced it with thing 7059. I can't find the corner bracket file I used to stiffen up the frame but I'll post it when I do. I also bolted together my "Z" carriage because it wanted to split with putting the tool holder one it.
If you have any questions or want me to make other upgrade/ design changes just let me know.
Thanks and I hope you put these files to good use.

This thing is based on the Cuboro Marble track, but I didnt have one when I drew the pieces. The track is 22mm diameter and all turns are 22mm radius too.
Feel free to add new parts.

My grandfather Karl Bier was a first-class maker and architect. He died when I was very young, so I never knew him, but I have some of his furniture in my house, and his level of craftsmanship has always inspired me.

He made a burr puzzle out of hardwood that we still have. It has a shine and finish that comes from many, many hours of being handled in the 60 or so years since it was made.

I've modeled an exact replica of that puzzle, and I hope people have as much fun with this one as I did over the years with my grandfather's wooden one.

parametric cube puzzle

This is a slightly more challenging variant of Dovetail Triangle that only opens when held in a certain orientation.

Watch the video for a demonstration:

The big and probably very hard one (20x10x3 paths) is inhomogenous!
One side (longest axis) has long pathways with few forks and almost no four five and six-way forks (labyrinthical) the other side has lots of short paths dead ends and more four five and maybe six-way forks (mazeical). There is no sharp border between those regions.

The medium sized one (12x12x2 paths) is
overall more "labyrinthical".

This object is a puzzle with a picture of the logo "R" and a field hockey player on it. It can be used as an activity or put in a frame for decoration.

The Penrose tiles by pleppik got me thinking and I decided they would be cooler if they held together on their own. The snap shapes enforce the matching rules (as long as all the pieces are right-side up), which means any pattern you make out of them will be aperiodic.

A marble maze made from wood (1.1" x 0.20" Pine).

This Thing adds the ability to add text onto the Soma Cube pieces. Useful for creating gifts or labeling solutions to the puzzle.
You can also create a sphere in the middle of each cube to place a neodymium magent in while printing.

The 3D Tangram as envisioned by my grandfather William Perkins.

Takes the 7 piece tangram and extends it into the third dimension by making it a pyramid.
Can be used as a puzzle to recreate the pyramid, or new shapes can be made by reorganizing the 7 pieces.

See en.wikipedia.org/wiki/Tangram for info on the Tangram.

This is my take on the worlds oldest continuously played board game Go. Dating back over 2000 years.
en.wikipedia.org/wiki/Go_game

This started out as a way to make a Go board that could be played in a moving vehicle, but it quickly morphed into what you see today. This modular set of Go board pieces can be used to create any n*n size Go board you want as well as arbitrary shapes. If really adds a new dimension to playing Go when you have obstacles or other shapes.

Each piece contains a 5 mm magnetic ball and is free to rotate inside the piece to create a perfect alignment with the center of the grid. I would imagine this board would be useful for people that lack the fine motor skills to accuracy place pieces on a standard Go board.

After giving kids another pile of 20mm calibration boxes and seeing complete lack of interest in the eyes, it struck me that the boxes can be used as tiles for a puzzle game I saw a long time ago. The only thing it needs is a box and 15 tiles with numbers. The tiles are mixed at the start and the goal is to arrange them in order by sliding into the only free spot available (without taking out of the box).

P.S. If you want to make a nice print of this puzzle rather than find a way to reuse a pile of the calibration boxes take a look at the thing already available on the Thingiverse: thingiverse.com/thing:15377

I wanted to recreate an old game that reminds me of my childhood, when there were no Playstation, PSP or similar. Can even today be a nice gift for a child "modern" ...

The zip file contains 15 file.stl of the individual numbers, for those who prefer this printing solution.

Looking to remake of the original puzzle by Sabu Oguro, I stumbled across a set of dxf files for each piece already on thingiverse
thingiverse.com/thing:1453

I ended up modifying each file to round off the corners and create a single path for the laser to cut around, I also added a tray to hold all the pieces in the basic shape.

Hello everyone, first of all I want to introduce myself. My name is Raúl Pérula - raules.wikispaces.com/Inicio - and I am student of Master in Robotic and Automation, University Carlos III of Madrid.

This project belongs to the development project of OOML - iearobotics.com/oomlwiki/doku.php -. OOML is simply a C++ empowered OpenSCAD. If you want more information enters OOML oficial website and inform yourself, sure you will be passionate the project and want to collaborate.

Using OOML I have made a library of objects to form structures with blocks. I have created different types of blocks to have considerable diversity. There from the simplest block, which is a simple piece consists of a cube with two linkers (a hole bottom and a top flange) to more complex blocks with different shapes such as L or T.

I have done a video showing how you can use this thing so useful. The pieces are not very accurate but I think when 3D printers improve and accuracy is not a problem can be made large structures.

This is a Pencil holder made of methacrylate. It have 3 pieces but you do not need glue.

Se trata de un portalapices hecho de metacrilato. Esta formado por 3 piezas que encajan unas en otras, se puede montar y usar sin necesidad de pegamento.

This is a 3D tic tac toe board and pieces.

A simple puzzle. This new .stl File should work. If any problems occur please state it in the comments.

This is a quick print self standing Christmas Tree. I wanted to give a present to the world and I thought that this would be a good gift.

This is a most simple design for a laser cut LED candle. The LED is powered by a coin battery cell. You can use any LED. Most realistic is a special yellow flashing blink LED as you can find them on ebay.

I loved this playsets simplicity but since I don't have a laser cutter I needed to make it 3D to print on my UP!
I plan to print them this weekend and hope the British can hold out long enough for those Martian invaders to catch a cold and die!

Printed 3 Martian war machines and 4 tanks, worked great!

Designed to test X and Y calibration, this test will show you which axis needs work and by how much. NO CALIPERS REQUIRED!

"NOTICE: This test presumes that your calibration is close on x and y and that your extruder is dead on. Filament size can effect internal holes and exterior diameter if not correctly calibrated.

This is to reconcile the axis against each other and ensure printed parts will fit into each other as expected.

The procedures mentioned here are my own and may have flaws I did not foresee."

The parts are labeled with the axis they are printed on length wise.

So, each axis and should show true. (Meaning the X Bar should fit the X slot even if the machine is off, same for Y bar and Y slot.)

The bars start with 20mm long and work down to 19.7mm. All bars are 5mm wide.

The slots are both 20mm long and 5.2mm wide (To allow you only test length).

I will post a full write up soon on the exact procedure to use this test.

A practice design for trying out techniques for making jigsaw puzzles using Inkscape and a laser cutter.

The puzzle is 77 pieces, with four shaped piece groups (sea turtle, moorish idol, and a pair of flip-flops). It also has an internal corner. Great for a fun memento of your tropical vacation.

This is a 3D puzzle that, when fabricated and assembled, forms a cube. See willykjellstrom.com/endover-puzzle/ for additional information.

I've been at it again. When I did that I-beam some time ago, I made a desk shelf that I'm still using in my office. The idea behind it is that a small shelf can sit on a desk and actually give you more surface area because you have an accessible second level. Clearly, there are diminishing returns. If you covered your desk with them, it wouldn't work so well. One or two, though, can actually help. You can see from the picture that from the year or so I've been at 3d printing, I've accumulated a lot of objects. My wife, out of frustration, threw them in a box. She seems to like the desk shelf though.

It is a puzzle. Impress your friends!
...
Well, impress the ones that don't know too much about 3d printing =)

I just made a 6 piece plate for this design.

A tangram is a 7 piece puzzle that can be put together to create a square. It is a very addicting puzzle that once you pick up, you can never put it down!
