CheapCAD Tools makes complete, ready-to-use mechanical parts from a description. Each of its three generators is a parametric program that builds the part to the published standards and the makers' data, and checks every setting against them: - Timing Pulley Generator: GT2, HTD, T5, AT5, XL, MXL and 30+ more belt profiles (ISO 13050, ISO 5294 and ISO 5296, and the belt makers' tables); printed or metal flanges; two-pulley drives with the belt. - Sprocket Designer: ANSI 25 to 240 (ASME B29.1), ISO 606 B-series and bicycle chains, single or multi-strand; bicycle cogs and chainrings; spokes; two-sprocket drives with the chain. - Gear Designer: involute spur, helical and herringbone gears by ISO 54 module or diametral pitch on the ISO 53 rack; meshing pairs, internal rings and racks; DIN 3960 profile shift and DIN 3967 backlash. All three take round, D-flat, ISO 773 keyed, ISO 14 and ISO 4156 splined and hex bores (including FRC ½" rounded hex) with DIN 471 retaining rings, and hubs with set screws held by the plastic, a captured nut or a heat-set insert. Describe the part the way you'd describe it to an engineer. Claude looks up every parameter the generator has, builds the design, and checks it against the standards. When a check finds a problem, such as a pulley face too narrow for the belt, a chain too short for its sprockets or an undercut gear tooth, Claude applies the generator's own Auto-fix and tells you what changed. Designing and checking are free. When you want the files, Claude quotes the token cost and, once you agree, gives you a download link for STL (with your print compensation), STEP at true size, DXF or SVG. Tokens are taken only when you open that link in your browser, never by Claude. The generators were written with Claude Code.
