Client-side calculators built for our own workshop floor, alongside a curated index of the best open-source CAD generators, slicer helpers, and calibration tools.
Real Margins Across Platforms
Calculate what a print actually costs you to make. Factors in filament, power, machine wear, labor, and packaging, with built-in fee presets for Etsy, eBay, direct cash sales (no fees), or custom platform cuts.
Scale-to-Meters Math
Weigh an open spool on your scale to see how much usable filament and length you have left before starting a long print.
Caliper Math for Clean Fits
Quick math for single-wall flow calibrations, hotend speed limits, and hole shrinkage offsets so parts snap together without filing.
Custom OpenSCAD Variables
Plug in your storage box row width and partition wall thickness to generate custom dimensions for Cold Snap dividers and stoppers.
Trusted third-party generators, clearance standards, and browser modeling tools.
Generates sacrificial fin structures for stabilizing tall, narrow prints without clumsy brim networks or print failure.
Custom bin, baseplate, and divider generator for the Gridfinity modular workbench organization system.
Instant parametric model generator for organization trays, divider boxes, sliding lid cases, and wall-mount fixtures.
Accessible web-based constructive solid geometry editor. Great for quick bracket modifications, text embossing, and boolean cutouts.
Full-featured parametric CAD running entirely inside your browser. Perfect for precision mechanical assemblies, mates, and sketches without installing hefty software.
Online WebAssembly compiler for OpenSCAD scripts. Write code and render 3D geometry directly in your browser without local installs.
Step-by-step walkthroughs for extrusion multiplier calibration, pressure advance tuning, first layer squish, and cooling limits.
Inspect toolpaths, travel moves, retraction points, and speed gradients layer-by-layer before sending files to your printer.
CNC Kitchen and McMaster hole sizing reference for designing thermoplastic heat-set bosses that seat clean and will not strip.
A broad index of quick web utilities including plastic shrinkage compensators, nozzle flow limits, and unit converters.
Trusted archives and model repositories for downloading STLs, 3MFs, and verified print profiles.
Bambu Lab's platform built around verified print profiles, multi-color filament setups, and community contests.
Prusa's clean, maker-focused model repository with clear licensing, verified makes, and regular themed design challenges.
Creality's model platform featuring printable STLs, design competitions, and direct cloud slicing presets for Ender and K-series machines.
The largest historical library of free 3D printable designs, replacement parts, and open-source hobbyist upgrades.
If there is a reliable open-source generator, calibration standard, or calculator you keep bookmarked, send it our way so we can add it to the directory.
