For Bambu Lab owners

The easy AI way to design for your Bambu Lab printer

Works with A1 mini, A1, A2L, P1S, P2S, X2D, H2S, H2D, H2D Pro, H2C and H3C. No CAD to learn: describe the part, check it in 3D and download an STL for Bambu Studio.

Start designing

Describe the part

Type what you need in plain words, start from a photo, or pick a shape from the library.

Set your fit once

Pick your printer, filament and nozzle. Millmetra saves thread, hole, peg and sliding fits for each, so parts fit the first time.

Open in Bambu Studio

Download the STL. Millmetra picks a good print orientation and splits big parts to fit your bed. Open it in Bambu Studio, slice and print.

Try a prompt like

“A spool holder for a 75 mm spool hole.”
“A clip that holds the AMS feed tube to the back of the printer.”
“A drawer to sit under an A1 mini, 180 mm wide.”
“A tool tray for an A2L, 320 mm wide, with three slots.”
“A mount that holds an H3C or H2D filament hub flat on the shelf.”
