The prompt
Create a modular ion-exchange column in Onshape with a 60 mm long, 12 mm OD body and a 4 mm central bore, plus removable top and bottom caps, porous resin-retaining frits, and seals. Add aligned inlet and outlet ports with 1/4-28 UNF female threads for compatible Elveflow fittings for 1/16-inch tubing. Label the wetted materials and pressure rating as “verify for intended chemistry and fittings” before fabrication or use.
