Generate an STL file for 3D printing.
Turn a description into a watertight, slicer-ready STL for FDM and resin printing. Manifold meshes that load into Cura, PrusaSlicer and Bambu Studio without repair.
STL is the standard mesh format for 3D printing. AiCadGen generates watertight, manifold STL directly from your description, so the file slices without holes or non-manifold edges. Because the part is modelled from real geometry first, dimensions are accurate — ideal for functional prints, not just decorative shapes.
- Watertight, manifold meshes — no repair before slicing.
- Dimensionally accurate, generated from a real solid then exported to mesh.
- STEP also available if you want to refine in CAD before printing.
- $Replacement knob, 30mm, 6mm D-shaft, knurled grip
- $Enclosure for a 60x40mm PCB, USB-C cutout, 4 standoffs
- $Cable clip for 8mm cable, screw mount, snap fit
Frequently asked questions
Will the STL slice without errors?
Yes. Output is manifold and watertight, accepted by Cura, PrusaSlicer and Bambu Studio without mesh repair.
Can I control tolerances for fits?
Specify the clearance (e.g. "0.2 mm clearance on the 8 mm bore") and it is applied to that feature.
Can I also get a STEP file?
Yes — the same model exports as AP242 STEP if you want to edit it in CAD before printing.
