Example prompt
Create a 4-channel relay DIN case, 77×57×22 mm cavity, four M3 standoffs, terminal slots, input header slot, 35 mm DIN clip, 2 mm walls.
What a 4-channel relay module din rail case is
A DIN rail case for a 4-channel 5 V relay module (about 75 × 55 mm). The cavity is 77 × 57 × 22 mm with four M3 standoffs, open slots over the three screw terminals of each relay, a slot for the input header and a clip for 35 mm DIN rail on the back. Walls are 2 mm. Print upside down in PETG or ASA.
The 1- and 2-channel modules are much narrower and slide around inside. Mains wiring still needs a proper certified enclosure. Open the ready-made model in SpeakCAD for free, change the size, then download the STL.

Start from this working example and replace any number with what you measured: Create a 4-channel relay DIN case, 77×57×22 mm cavity, four M3 standoffs, terminal slots, input header slot, 35 mm DIN clip, 2 mm walls.
The 1- and 2-channel modules are much narrower and slide around inside. 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.
