Example prompt
Create an HC-SR501 PIR case, 33×25 mm board bay, 23.5 mm dome hole, two 2 mm pot access holes, 5 mm cable slot, 1.6 mm PLA walls.
What a hc-sr501 pir sensor dome case is
A case for an HC-SR501 PIR module (32 × 24 mm board) that lets its 23 mm Fresnel dome poke through a 23.5 mm front hole. Two 2 mm access holes line up with the sensitivity and delay pots, the board sits on standoffs at the 28 mm hole spacing, and a 5 mm slot feeds the three-pin cable. Print in PLA, front down, 1.6 mm walls.
The AM312 mini PIR is only 10 mm across and falls through this hole. Open the model in SpeakCAD without paying, 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: Create an HC-SR501 PIR case, 33×25 mm board bay, 23.5 mm dome hole, two 2 mm pot access holes, 5 mm cable slot, 1.6 mm PLA walls.
The AM312 mini PIR is only 10 mm across and falls through this hole. 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.
