Essential Modeling Resources
Tools, software, and references we actually recommend for scale modeling, model railroading, and miniature work — alongside the scale calculator itself.
Measuring & Marking
- Digital calipersThe single most useful measuring tool on a workbench. A basic 150 mm/6″ caliper with a metric↔imperial toggle covers almost every modeling task.
- Architect’s scale rulersTriangular rulers marked directly in common ratios (1:50, 1:100, 1:200) let you read scaled drawings without converting at all.
- Steel rule + cutting matA rigid steel rule doubles as a straightedge for cutting; printed paper rulers stretch and curl.

Free Software
- BlenderFree, open-source 3D suite — great for sculpting miniatures and terrain.
- FreeCADOpen-source parametric CAD for dimensioned, engineering-style parts.
- Slicer tip: scaling STLsTo print a full-size STL at 1:56 (28mm), set your slicer’s scale to 100 ÷ 56 ≈ 1.786%. Use the calculator to get exact percentages for any ratio.
