Shelly 1 Mini Gen3 DIN rail adapter clip
A clip that mounts a Shelly 1 Mini Gen3 relay onto a standard 35 mm top-hat DIN rail inside a consumer unit or junction box. The Shelly 1 Mini Gen3 is about 34 x 38 x 16 mm, so the adapter is a 40 x 45 mm base with a 35 x 39 mm pocket, 0.4 mm clearance, side walls 12 mm tall that leave the screw terminals and the antenna edge exposed, and a sprung DIN hook underneath with a 2 mm flex tab that snaps over the rail. Walls are 2 mm and the hook lands on the print bed so the part needs no supports. Print in PETG or ASA for the temperatures inside an enclosure.

Fit notes
Shelly does not sell a DIN clip for the Mini, and generic downloads target the larger Shelly Plus 1. In SpeakCAD you describe the relay, preview the clip in the browser, adapt it to a Shelly Plus 2PM or a Sonoff Mini R4 in the chat, and download the STL.

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.
