Example prompt
Model a 2S 18650 pack holder, 38×67×20 mm cell bay with separator, nickel strip slots, 48×22 mm BMS pocket, lid, 2 mm walls.
What a 2s bms and 18650 pack holder is
A holder for two 18650 cells in series (each 18 × 65 mm) with a 2S BMS board (about 46 × 20 mm) on the side. The cell bay is 38 × 67 × 20 mm with separators and nickel-strip slots, the BMS pocket has a 1 mm gap for air, and a lid covers both. Walls are 2 mm. Print in PETG or ASA, not PLA.
A 4-cell parallel box has no room for a BMS and wires cells differently. Open the ready-made model in SpeakCAD for free, adjust the cell pocket for protected cells, then download the STL.

Start from this working example and replace any number with what you measured: Model a 2S 18650 pack holder, 38×67×20 mm cell bay with separator, nickel strip slots, 48×22 mm BMS pocket, lid, 2 mm walls.
A 4-cell parallel box has no room for a BMS and wires cells differently. 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.
