3D printing tools
Calculators, model makers and references for 3D printing and modelling. They all run in your browser, they're free, and there's nothing to sign up for or install.
Printing
Plan prints and know what they'll cost.
-
Turn grams or metres of filament into a cost per print.
-
A rough print time and filament use from an STL or the model's size.
-
Convert between spool length and weight for any diameter.
Calibration
Get the machine square and the extrusion right.
-
A labelled test tower for finding the best temperature for a filament.
- E-steps calculatorComing soon
Work out new extruder steps per mm from a test extrusion.
- Flow rate calculatorComing soon
Correct flow from a measured single-wall print.
- Skew correctionComing soon
Turn diagonal measurements into a skew correction factor.
Make
Fill in a few boxes and download a model ready to print.
-
Storage bins in any grid size, with dividers and a label shelf.
-
Caps for the square corners of shelves and table tops, sized to your board.
-
Raised-letter tags with an optional keyring loop.
-
Make a QR code as an image, or as an STL to print as a sign.
-
Turn a photo into a flat or curved panel that shows the picture when lit.
Modelling
Check models and size things so they fit.
-
Open an STL in 3D and check its size and volume before slicing.
-
Millimetres, inches and model scales like 1:35 or 28mm.
-
Suggested gaps for press fits, sliding fits and hinges.
-
Typical temperatures and quirks for PLA, PETG, ABS, TPU and more.
