Nice collapsible carrot which can be magically pulled from your hand. Or from a combination safe lock box or from an egg shell . Prints mostly in place, just the carrot tip have to be inserted into the collapsed carrot body and pushed…
Puzzle for everybody. Try to arrange individual pieces into a 4x4x4 cube. Maybe your grandchild will do it. Maybe you will go mad before solving it. You have been warned. There are at least 133 solutions of Evil Cube. Super easy PLA (or…
Flow a polystyrene ball! Try to go as high as you can and then land it back safely. Apart from demonstrating interesting physics of the air stream, it also teaches you to control your breath. This helps for singing and playing musical…
The legendary @ kriswillcode 's Fidget Toggle Switch, a bit fine tuned for mass use, durability and easy print for all friends and friends of friends. Click once and you are hooked. Really addictive. Use a tiny bit of candle wax on the…
UPDATE: You certainly want the new krab-stand* version which has only positives and none of the negatives mentioned below. Print them all at once, perfectly! Shape is slightly improved for printing in the standing position. Bowls are…
PLA, layer 0.2mm. Easy print in place. Re-shaping it in your hand is a bit addictive. The surface touching the printing plate is a 6-star, big enough to stay safely attached when printing with PLA. Of course you can use PETG as well but…
Protein folding kit made especially for better understanding of AlphaFold2 and OpenFold code. Pymol is great but touching macromolecules by hand is better. Print in PETG without any support or brim. For C+O+Ntetra+P.stl and Hydrogen.stl…
Both a Nobel prize winner and a child can learn with this model. As a child, I've seen a safe-type combination padlock but could not guess what is inside. Years later, Feynman explained it to me in his book. It was a double pleasure: I…
Cookie cutters easily made from svg using OpenSCAD. It is just a Minkowski of the SVG letter outline and a tall cone, see Chi.scad. The shapes in hand somehow happen to be quite toxic for both Inkscape and FreeCAD so I had to use these…
Track any daily event - like your daddy taking a pill. Mark days of week on the container using a CD pen, do the 5 minutes print, snap it on the bottle neck - and always know whether the tracked event happened that day already or not yet!…

Movable connection fixing an ever breaking point of that cheap thing called Paloma. Just cut a clean end of the broken pipe - the green part goes to it.
The gcode has several filament changes in it expected to be done by hand. The printer will tell you what to do. See the photo for my colors or design your own combination. I did it in transparent PETGs and it looks quite nice. Attention:…
Tool for easy closing of bigger zip bags which are hard to seal by hand. You will love closing your bags now! Easy no-supports print. I printed it in PETG with 0.3mm layers but PLA or other materials should work as well. You still need to…
Cheap microscopes are basically a web camera with a different lens - not much to do wrong on these (it is just reuse of web camera parts), apart from the stand which totally sucks for sure. But you can 3D-print a better one :) I wanted to…
Got home from hard work on Monday. Make your day even better by rearranging the furniture! New game every day, till Thursday. Friday you can rest.
An easy to print egg holder which can in fact hold other things as well, e.g. a collapsible carrot . Super easy fast print without supports using any material. Tune the size to your local egg market - the one with egg on my picture is at…
It's magic. Just throw it as a dice. If the smiley side is anywhere visible, you will have a lucky day. If it is at the top, it means an especially good day for love, art, business, sport and 3D printing. Or just anything you do :) If you…
The trackball3D is a computer input device made for any axis rotation of camera view in pymol molecular visualizations. Unlike traditional 2D input devices like mouse, trackpad or ordinary trackball, this device senses rotations of a ball…
