3D modeling for your printer, right in the browser
Build the part from parametric shapes, drill it with real boolean operations and export it as binary STL. See the volume and estimated PLA weight before the printer starts.
Parts from parameters
Rounded box, cylinder with different top and bottom radius, prism with any number of sides, tube with a wall thickness, gear with module and tooth count, bolt with a real thread pitch. Change a number, the part changes.
Holes that survive into the STL
The boolean difference produces true geometry, not a visual trick: the hole exists in the exported file too, so your slicer sees exactly what you drew.
How much material it takes
The analysis panel shows part volume, estimated PLA weight and approximate filament length, so you know the cost of a print in advance.
Formats
Binary STL for printing, OBJ for exchange with other programs and GLB for web or presentations. You can also import STL, OBJ or 3MF to modify an existing part.
