Check a model, price a part, pick a material — instantly, in your browser, no signup. Built for makers and the people who hire them.
Drop in an STL and see if it's printable — watertight, manifold, and bed-fit checks with a 3D defect view.
LIVEBallpark what a part costs to fabricate — by process, material, size and quantity — then get real quotes.
LIVEAnswer a few questions about your part and get the right material and process, with the tradeoffs spelled out.
LIVEConvert between grams, length and cost for any filament — and check what's left on a partial spool.
Spindle RPM, feed rate and removal rate for milling and routing, with material presets. Metric or imperial.
LIVETap drill sizes, thread pitch and clearance holes — metric and imperial, M2 to M20 plus UNC/UNF.
LIVEInvolute spur gears to spec — module, teeth, pressure angle, bore — with a live preview and SVG download.
ISO shaft/hole fits (H7/g6 and friends) with clearance and interference.
Bend allowance, deduction and flat-blank length with K-factor presets. The core sheet-metal calc.
Bending force by material, thickness and V-die width.
Sheet gauge to mm/inch for steel, aluminum and stainless.
Weight of any stock — plate, bar, tube, square, hex — across metals, plastics and wood.
LIVEPack cuts onto the fewest stock lengths and see the waste — bar, board, tube or extrusion, kerf included.
Fillet weld throat and load capacity.
Estimate cut time and cost from toolpath length, and dial in kerf compensation for press-fit parts.
LIVETune a staggered slit pattern, preview it live, and download a laser-ready SVG that makes rigid sheet bend.
Dimensions in, laser-ready box panels out as SVG.
How much silicone or resin to mix, two-part ratios by weight or volume, and shrinkage compensation.
Break-even quantity between molding tooling and printing per-unit.
IPC-2221 trace width for a given current, and the LED series resistor with nearest standard value.
Microstrip impedance and resistor color-code decoder.
Estimate fabric yardage for your pieces and price an embroidery job by stitch count.
Per-garment screen-print costing and vinyl sizing.
Lumber volume and cost, plus shelf-sag/span deflection.
Dimensions in, laser-ready box panels out as SVG.
Bending force by material, thickness and die width.
Describe what went wrong with a print and get the likely cause and fix.
