This is a very small OpenSCAD snowflake/star design. I designed it so its arms are printed with 2 lines on my makerbot setup.

This is a modified version of my old Reuleaux Triangle design. Instead of screws it uses snap fitting pieces to hold the 3 layers together. Therefore it is a completely lazzzorcut design :)

The "screwlessness" was inspired by the "Screwless Cube Gears" by emmett thingiverse.com/thing:10483

For years I wanted to print a spintop. But with the geared motor extruders this was not possible because the pointed tip would accumulate too much heat and melt away because with a geared motor you can not exactly control the amount of extruded material which is just what you need to do when you want to slow down in the upper layers to give the plastic more time to cool down.

Now that we have stepper motor based extruders it's possible so I just HAD to create this object using OpenSCAD :)

The snap fit handle (needed to keep the lower part flat and printable) was inspired by the printed axis in the "Screwless Cube Gears" by emmett thingiverse.com/thing:10483

Arrrrr!!! Since this is a special day I decided to lazzzor something for the occasion.

Inspired by thingiverse.com/thing:10620 but I waned to remodel something similar in openscad to be able to make the hole bigger because my printer makes the holes smaller than they should be.

Continues the theme of thingiverse.com/thing:3272 :)

The spheres stack into each other like Matryoshka dolls en.wikipedia.org/wiki/Matryoshka_doll

After my initial not so successful attempts to create a snapping sphere I had a chance discovery when I tried to put a ball inside the two sphere halves and noticed that although the two parts of the sphere don't hold onto each other they both snap to the slightly smaller ball in the middle...So I went back to the original symmetric Demi-Sphere thingiverse.com/thing:3068 for the shell but added an inner sphere (without the hard to print top and bottom tips) to hold the two demi-sphere parts together. Snaps like a charm.

I loved the Hollow Demi-sphere thingiverse.com/thing:3068 but I was a little bit disappointed when I found out that it does not snap fit and falls apart by itself. So I remodelled it in OpenSCAD and then changed the angles of the cut out cones to get a snap-closing sphere that does not fall apart by itself. The only drawback compared to the Demi-sphere is that the two parts are not identical anymore, but they are still very good for printing as they are both flat on the bottom (the larger part is also flat on the top).

I modelled this for a friend. Stove knobs are the real reprap killer application.

A python script to generate OpenSCAD models to generate two parts of a box that screw together and snap fit if you find your way through the maze :)

A box that screws in a zigzag way. Python generated OpenSCAD model.

Since OpenSCAD does not support variable reassignment and recursion I wrote some python glue code to generate OpenSCAD models.

Now we can haz Turing Complete Models :)

There is an improved version of this available: thingiverse.com/thing:1414

Features include:
* Arduino controlled so it can blink in different speeds, colorfade, etc. AND you can reprogram it to make whatever you want.
* Three pots to set the red, green and blue LEDs.
* reprap printed knobs for the pots
* Osram RGB LED (almost perfect point light source) with 30mA per color.
* exchangable stencil
* one rotating axis to project onto a wall or the ceiling.

I found the warning sign in a blog post about future warning signs lifeboat.com/ex/warning.signs.for.tomorrow and immediately knew that I needed such a sign for my Makerbot.

Because the original pictures are very low-res the auto vectorizing did not work out too well so I redrew it as a dxf using a stencil font.

A friend who works in data recovery often needs to handle many hard drives and have then easily accessible.

So yesterday we had a small CAD'n'lazzzor session and we created this mount for 8 hard drives. It's cut from 2mm HDPE. The orange thing is rubber to prevent the disks from gliding away when you move the mount.

UPDATE: You might want to use the new screwless version of this design I made: thingiverse.com/thing:12644

A curious shape with constant width. It rolls smoothly in a square but the centre of rotation is not constant.

people who have been to HAR might recognize this...

The Gear I created with cliffords Gear Script (http://www.thingiverse.com/thing:829) and the Rack I created using my own quick and dirty experimental Rack Script (https://whatever.metalab.at/user/wizard23/RackGenerator) which takes a closed loop (like a gear or a star, or a heart) and creates the fitting rack for rolling this object.

These were my design goals:

- Built entirely out of cardboard
- Does not need any glue (all the connectors snap into place)
- still mechanically stable

This is the 5th iteration of the design and finally it meets all these goals:)

I always liked Escher's irregular tessellations but when I saw this picture with my new lazzzor eyes I thought WOW this is perfect it leaves no waste material :)

This is the final design that evolved out of my lasercut snapping connector tests I did here: thingiverse.com/thing:942

this is an evolutionary thing-thread that aims to explore snapping connectors that can be made with the 2D capabilities of a laser cutter. I don't delete the designs that did not work out because they show what does not work.

Glow stick brackets to connect glowsticks with 6mm diameter.

This was inspired by the cover of the famous book "Gödel, Escher, Bach: An Eternal Golden Braid" by Douglas Hofstadter

this was modelled by clifford.at I just uploaded it to thingiverse
