Enclosure for a relay module with terminal access
A protective housing for a one- or two-channel relay module that hides live terminals while leaving the screw terminals reachable through a slot and the control pins available on the opposite side. The base has 3 mm standoffs on the module's hole pattern, 2 mm walls and a 14 mm high terminal slot along one long edge that also keeps fingers away from the contacts. The lid screws down with two M3 fasteners and includes a small window above the indicator LED. Print with the open side up for clean cavities. 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?

Example prompt
Create an enclosure for a 2-channel relay module 50x38 mm, holes 2.5 mm from corners. Cavity 52x40x22 mm, 2 mm walls, 3 mm standoffs with 2.5 mm holes. 40x14 mm terminal slot on one side, 20x8 mm pin slot opposite, 4 mm LED window, two M3 lid screws.
Fit notes
Relay modules are sold in countless layouts, so SpeakCAD draws the standoffs and slots where your particular board needs them. Preview in the browser and ask for a DIN rail foot, a strain relief for the mains cable or a taller cavity for the wire loops.

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.
