Vented case for a Raspberry Pi 4
A two-part shell for the Raspberry Pi 4 that protects the board while keeping it cool, with cut-outs for USB, Ethernet, HDMI, audio, USB-C power and the microSD slot. The base carries four 2.5 mm posts on the 58 x 49 mm hole pattern, walls are 2 mm with 0.5 mm clearance around the board, and the lid snaps on with four cantilever tabs. A grid of 3 mm hex vents over the CPU and a 30 mm fan opening keep temperatures down under load. Open the ready-made model free, resize it on your phone or computer, then download a print-ready STL, 3MF or G-code sliced for your printer, free.Opening the ready-made model and downloading it as STL or 3MF are free, no card; AI changes use credits, from Maker at $7.99 a month.No printer?

Design a two-part case for a Raspberry Pi 4 (holes at 58x49 mm). Walls 2 mm, 0.5 mm clearance, four 6 mm posts with 2.5 mm holes. Cut-outs for USB-A, Ethernet, micro HDMI, USB-C, audio and SD slot. Snap-fit lid with 30 mm fan hole and hex vents.
Fit notes
With SpeakCAD you decide whether the lid has a fan hole, how much room a HAT needs or whether the GPIO header stays accessible, and the case is generated to match. Open the ready-made model free, change its numbers in the viewer and download the STL or 3MF free; AI changes use credits.

A shared STL is modelled for someone else's measurements. Here you open the ready-made model free, change it to your measurements in the viewer, then download a file sized for the part you actually own, free as STL or 3MF.
Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
