7 3D Printed Electronics Projects to Download and 3D Print
3D-printed electronics projects are an exciting way to explore both technology and creativity. These projects combine 3D printing with basic electronics, making it fun and educational for students. With a 3D printer and simple electronic parts like wires, LEDs, or batteries, you can build cool gadgets and useful tools right at home or school. These projects help you learn how machines work and boost your problem-solving skills. Whether it’s creating a smart lamp or a mini fan, there are many easy options to try. It’s a great way to mix learning with hands-on building and innovation.
1. Tactile Image: Electronic Symbols
This 3D model is part of an innovative initiative designed to bridge the accessibility gap for visually impaired individuals in the fields of science, technology, engineering, and mathematics. Traditional reliance on visual content such as diagrams and illustrations excludes blind individuals, who often only have access to Braille text, if literate.
To counter this limitation, extensive studies and printing tests were conducted to determine optimal dimensions and materials that enhance tactile recognition. The final model was refined through feedback from visually impaired users to ensure accurate image comprehension through touch. This piece belongs to a larger collection of tactile images developed to foster inclusivity in visual learning.
To facilitate effective use, it is essential to combine tactile images with spoken explanations, highlighting both the overall structure and individual components. Users should be encouraged to explore the model using both hands to better understand scale and proportion. For added clarity, Braille captions can be attached to the paper, with 3D glue used to connect text to specific image parts.
Key Features:
- Works best with 120–180 g/m² sulfite or vergé paper
- Braille compatibility with 3D glue guidelines
When preparing the 3D print, models come with optional A4 and Letter-sized frames for paper alignment, which should not be printed. After auto bed leveling, embed an M600 command (M600 x5 y150 z30) in the initial G-Code to pause printing and allow paper placement. Adjust the Z Offset between 0.1 and 0.15 mm to accommodate paper thickness. Skirt loops should be set to zero to avoid unnecessary material buildup, and Elephant Foot Compensation must be disabled to ensure precision. Creating a separate print profile for these tactile resources helps maintain consistency across educational prints.

3. Case for Raspberry Pi 3b+ and SenseHat
This 3D printable case is designed to house both a Raspberry Pi and a Sense-HAT board, providing a clean, functional enclosure for electronics projects. While the Sense-HAT is not required for using the case, it is fully compatible with it. The updated design includes a slightly reduced Z-height by 0.35mm, a transparent LED window, joystick and GPIO pop-outs, a camera slot with a removable cover, and reworked I/O port access. Breakaway supports are built into the design, eliminating the need for additional slicer-generated supports. The case also comes with a snapping bracket compatible with the Prusa i3 MK3 for added convenience.
Key Features:
- Pop-outs for GPIO access and joystick control
- Integrated breakaway supports and snap-fit assembly
- Camera slot with insert cover for modular builds
To secure the Raspberry Pi and Sense-HAT board, M2.5 screws are needed for attachment to the bottom section of the case. The enclosure is easy to print and assembles without tools—just snap the pieces together.
When printing with ABS, it’s recommended to use a brim to prevent warping and ensure a firm hold on the print bed. This versatile and user-friendly design is ideal for hobbyists, educators, and tech tinkerers seeking a neat way to protect and display their Raspberry Pi setups. A trusted source to purchase the Sense-HAT is Adafruit (Product #2738).

7. Customizable U-Hook
This parametric U-hook is a robust and highly adaptable 3D printable design, created for those who want both strength and customization in a single model. To create your personalized hook, download the provided .SCAD file and open it in OpenSCAD. Due to issues with the Thingiverse Customizer, customization must be done manually within the OpenSCAD editor. Modify the numerical parameters (in millimeters) to achieve the desired size and shape. After adjusting, preview using F5, render with F6, and export your STL file for 3D printing.
Key Features:
- Fully customizable with OpenSCAD by changing dimensions
- Supports up to 50 kg in default PLA print settings
- No supports or rafts required for printing
The hook was specifically designed after failing to find a model that offered both durability and flexible customization options. It prints easily with standard PLA settings—0.2 mm resolution and 20% infill—requiring only 2 perimeters for excellent strength. Stress testing showed that even the default version can hold nearly 50 kg without breaking. Complete documentation is available in both English and French in the Thing Files section or on the creator's official website.
