Example prompt
Design an SCD41 CO2 sensor case, 25×25×10 mm sensor bay with 1.5 mm vent slots on three sides, separate 30×22 mm ESP32 bay, 4 mm cable hole, 1.6 mm walls.
What a scd41 co2 sensor case with side vents is
A vented case for an SCD40 or SCD41 breakout (the Sensirion module is 10.1 × 10.1 × 6.5 mm, most boards are about 23 × 23 mm) so the photoacoustic cell reads room air, not the ESP32's heat. The sensor bay is 25 × 25 × 10 mm, separated from a 30 × 22 mm controller bay by a 2 mm wall, with 1.5 mm vent slots on three sides and a 4 mm cable hole. Print in PLA or PETG, 1.6 mm walls, lid down.
An MH-Z19B or Senseair S8 is a much longer NDIR module and will not fit this bay. Open the ready-made model in SpeakCAD for free, change any millimetre in the viewer or the chat, then download the STL.

Start from this working example and replace any number with what you measured: Design an SCD41 CO2 sensor case, 25×25×10 mm sensor bay with 1.5 mm vent slots on three sides, separate 30×22 mm ESP32 bay, 4 mm cable hole, 1.6 mm walls.
An MH-Z19B or Senseair S8 is a much longer NDIR module and will not fit this bay. 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.
