Pulley for small experiments with a 30 mm wheel and holes of 3mm, you can use I with 4mm parachord.
You can perform 3-color Elephant Paste chemical experiment with this model.
3D files included here at Prusa Printers: All parts to make your own popSCOPE. 26x 3D printable QR-code microscope slides which are used to simulate real microscope slides 18x puzzle piece files (glued together to form 9 puzzle pieces in…
Made some experiments with hot glue, trying to create some parts with grip. It's essential to use melted butter all over the internal surfaces!!!! Super easy technic! Just be careful with hot glue!
Storage holder
These are a few stands for lenses, mirrors, LEDs and cards to help children play around with optical properties by freely moving them around seeing what they can do. Great for also calculating focal length of your 25 and 27mm lenses.…
Random Gridfinity things for sharing. You random viewer is probably not interested in this
We have returned with version 3.0 of SCOPES. Here we present boxSCOPE (aka PrusamentSCOPE)! This version of SCOPES is designed to make it even easier for young scientists to try out SCOPES and was inspired by other projects on the site…

Use this model as cheap spotting plate in chemical experiments.
The tracks have all the same height from the start to the realease point, so you can compare different angles, with nearly the same throwing speed. You can use carbon paper to measure the throwing distance depending on the drop height or…
"Present day, present time..." A 1998 Retro Terminal for Your Modern Hardware What happens when old-school cyberpunk design meets modern computing? It gets connected to the Wired. Inspired by the contest prompt to build a "little funny…
Description Exploring an alternative to the Gaggiuino Tubing Consolidation. Designed for modded Classic variants with active pressure and flow control (e.g. Gaggiuino). The intake tube should be moved to the right hole in the housing…
Stand made for experiments with ML image processing. As a board, Arduino Nicla Vision was used. As pipes, standard, aluminum extruded 12mm pipes were used. FreeCAD files attached if you want to modify them. List of materials: Item Length…
You can create galvanic cell battery using this model, fuit juice and pins of different metals (iron and copper).
Ground-based microgravity simulators, such as rotating 2D clinostats, are valuable tools for studying gravity-related processes. This work presents a versatile, g-value-adjustable 2D clinostat designed to hold a single 90 mm Petri dish.…
Create pH measuring scale with this model.
This is a simple frame for mounting a piece of tracing paper or other semi-transparent paper as a projection screen for optics experiments in physics class. Print ONE PAIR for a single frame. Other materials required 1cm long flat-head M3…
This glass cuvette holder was designed to be used for a set of glass cuvettes of different path lengths (d), namely 1 mm, 2 mm, 5 mm, 10 mm, 20 mm, 50 mm and 100 mm. This set is used in our laboratory to perform dilution experiments in a…
Yes, I know there's a cool library (Belfry OpenScad Library, v2) to achieve all sorts of mechanical parts, but sometimes someone wants to tinker around for themselves. The best working screws with my experiments are the ones with two…
A set of mirrors to mount on top of the Vernier angle ruler . Mirrors with different curvatures should reflect laser pointer light in a different ways. You can use cloudy water in a glass, smoke or vape steam to visualize laser pointer…
Here are some experiments and requests for cygnus keyboard. Cygnus top halve with a single 1.5u thumb key.
Unsupported Bridge Experiments – Remix for Ender 3 Pro (Klipper, Direct Drive) Remix of “ Unsupported Bridge Experiments ” by Make Wonderful Things . About The original model and its method worked perfectly on my Bambu Lab P2S. I wanted…
Motivation I wanted to show my kid how basic lens shapes effect light beams. It's interesting with a single laser but much more fun with several in parallel as seen in the attached images. So, I found some inexpensive laser modules online…
