Raspberry Pi 3B+ case
This is not a fixed STL. SpeakCAD generates the raspberry pi 3b+ case to your millimetres, you adjust it in the chat, then you download and print it.Adjust
Click a part and change its numbers in the viewer, or ask the AI in the chat: wall thickness, hole size, the thing it clips onto. AI changes use plan credits.Example prompt
Design a Raspberry Pi 3B+ case, 87×58×24 mm cavity, micro-USB, HDMI, audio, USB and Ethernet openings, microSD notch, M2.5 standoffs at 58×49 mm.
What a raspberry pi 3b+ case is
A two-part case for a Raspberry Pi 3 Model B+ (85 × 56 mm). The cavity is 87 × 58 × 24 mm with openings for the micro-USB power, full-size HDMI, 3.5 mm jack, four USB-A and Ethernet ports, a microSD notch and a slot for the camera ribbon. Walls are 2 mm with four M2.5 standoffs at 58 × 49 mm. Print both halves flat in PLA.
A Pi 4 or Pi 5 case has micro-HDMI openings and a USB-C slot in the wrong place. Open the ready-made model in SpeakCAD for free, adjust the openings, then download the STL.

The model renders in your browser, nothing to install. Change any millimetre in the viewer or the chat (AI changes use plan credits), then export a watertight STL or 3MF with a Maker or Pro plan when you want to print.
Start from this working example and replace any number with what you measured: Design a Raspberry Pi 3B+ case, 87×58×24 mm cavity, micro-USB, HDMI, audio, USB and Ethernet openings, microSD notch, M2.5 standoffs at 58×49 mm.
A Pi 4 or Pi 5 case has micro-HDMI openings and a USB-C slot in the wrong place. In SpeakCAD you open the ready-made model for free, change it to your measurements, then download a file sized for the part you actually own.
No. SpeakCAD runs entirely in the browser: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL or 3MF.
