This model was designed for my Makia track saw rails but could be adapted for any other rails, too. The fully parametric design can be accessed at onshape: Track Saw Rail Holder . The holders can either be fix on a wall or on the ceiling.…
https://www.tinkercad.com/things/6p7QvpgFpcQ-molekulbausteine One of my students designed these building blocks to introduce the empirical formula in chemistry based on an idea from a colleague. There is also a worksheet in the files…
This model can be used to get an impression of the physical term “pressure”. Pressure is defined as force per area and with this model the force applied by a weight can be distributed via 1×1, 5×5, 10×10 or 20×20 pins. Put the model on…
This model uses trays with different sized holes to sort metric hex nuts. Just stack the trays from small to big (smallest size the lowest in th stack), put in a handful of unsorted nuts, put the lid on and shake it. The nuts will fall…
The Brachio Lamp is a 3D-printed night light in the shape of a cute brachiosaurus dinosaur. The light can be dimmed in four steps, and an additional function is a pulsing/breathing light to help you fall asleep. All functions are…
These models can be used to test the sans fonts of onshape CAD in different sizes and you can change the demo text and size as parameters (see below). Print settings 0.4mm nozzle layer height: 0.15mm (4 layers total = 2 layers base, 2…
Info This is a case or holder for the Globe Demonstrator. A cool gadget by CDA GmbH using light interference to create images of star field, turning globes, the moon and their logo. You can find a demonstration at…
This is a counting aid for counting 100 mini dice. I developed this project for an experiment in physics lessons in which the “decay” of dice is investigated analogue to radioactive decay. Instructions at https://herrw.de/zerfall (only in…
I made this case to mount a presence detector to the ceiling of my workshop. I made the case a bit higher so the sensor can “see” below the other things hanging from the ceiling. Printing Print the case and three of the clips, with the…
This sensor can detect whether the attic hatch is open or closed. For this purpose, a pushbutton (Marquardt 1117.0206) is used together with a KNX binary input or a pushbutton interface (MDT BE-02001.02). Print settings general settings…
🇬🇧 In my class computer science / programming I use “Klaus” for an entry level course of programming and algorithm design. This is fully analog with cards to lay out algorithms. You can then ”run” these by placing a little figure on a…
