Field notes
The page lists five calculators spanning gears, beams, bolts, bearings, and O-rings. Examples include an ISO 6336 gear check, a bolt torque calculator for M3–M64 fasteners, and an O-ring groove tool covering AS568B dashes 004–028. Model-store listings include formats such as STEP, STL, and DXF; MechBench says results are for preliminary design and should be verified before manufacturing.
