Example prompt
Create a SEN55 case, 41.5×41.5×13 mm bay, separate inlet and outlet grilles with 1.5 mm slots, 6 mm cable slot, 35×26 mm controller bay, 1.6 mm PETG.
What a sensirion sen55 air quality sensor case is
A case for a Sensirion SEN55 (40.6 × 40.6 × 12.2 mm) that lines up its air inlet and outlet with two separate grilles and keeps the controller behind a wall. The bay is 41.5 × 41.5 × 13 mm, the grilles use 1.5 mm slots, a 1.25 mm JST cable exits through a 6 mm slot, and a 35 × 26 mm bay holds a D1 mini or ESP32-C3. Print in PETG, 1.6 mm walls.
The SEN54 and SEN55 share the same body, but a PMS5003 case is the wrong shape. Open the ready-made case in SpeakCAD for free, adjust it in the viewer or the chat, 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: Create a SEN55 case, 41.5×41.5×13 mm bay, separate inlet and outlet grilles with 1.5 mm slots, 6 mm cable slot, 35×26 mm controller bay, 1.6 mm PETG.
The SEN54 and SEN55 share the same body, but a PMS5003 case is the wrong shape. 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.
