Free 3D printing tools

Quick browser calculators for miniature and case printing — cost, scale, material use, print time and how many minis fit. No sign-up, nothing leaves your device.

◈

Cost calculator

Your true cost per print — resin or filament, power, failures, labour and machine wear — plus a suggested selling price.

⇲

Scale converter & STL resize

Convert between 28 / 32 / 54 mm and ratios like 1:56 or 1:48, and get the exact resize % and new dimensions for your model.

Filament & resin estimator

Turn a model's volume (or bounding box) into grams, metres of filament or millilitres of resin — and what it costs.

Open tool ↳
◔

Print-time estimator

Ballpark how long a print takes — volume-based for FDM, layer-based for resin. Handy before you commit the plate.

Case-size calculator

How many minis fit a tray, or what case size you need for an army. Then carve the real thing in the app.

Made for miniature & case printers

These are the small calculations that come up every time you print a mini or a carrying case — pricing a commission, resizing a model to the right scale, checking how much resin a batch needs, or working out what size case an army needs. They run entirely in your browser and are free to use.

When you're ready to protect those prints, carve a custom-fit case from any STL →
