Adapter Generator - Parametric Fittings & Elbows

Looking for a custom adapter, fitting, reducer, or elbow? Look no further. AdapterGenerator is a fully parametric OpenSCAD generator for hollow adapters. Configure End A and End B independently using round or rectangular spigots and sockets, hose barbs, male or female threads, or bolted flanges, then connect them with a straight, offset, reducing, stepped, or bent transition.   From vacuum hose adapters and duct transitions to threaded couplers, nozzles, reducers, and custom fittings, it's built for practical real-world connections.   A shared transition system keeps the workflow simple, while independent end geometry, fit allowance, taper, bends, seals, wrench flats, and finishing controls let you tailor the result to the connection you need.   Click Customize to open the generator. 🚀 Quick Start 1. Choose End A Select the first interface type and enter its size, length, and any interface-specific settings.   2. Choose End B Configure the second end independently. Mix sockets, spigots, hose barbs, threads, flanges, or rectangular fittings as needed.   3. Shape the Transition Set the transition length and optional offset. Use a length of 0 for an abrupt stepped connection.   4. Add a Bend Set the bend angle, radius, and rotation to create straight adapters or custom elbows.   5. Refine and Export Adjust fit, wall thickness, barbs, threads, O-ring grooves, flanges, and finishing details, then choose the desired output and quality.  ⭐ Features Mix-and-Match Interfaces Connect round or rectangular sockets and spigots, hose barbs, threads, and flanges. Flexible Transitions Create reducers, enlargers, stepped adapters, and eccentric or offset connections. Custom Elbows Add bends up to 180° with adjustable centerline radius and rotation. Functional Details Add tapers, hose barbs, wrench flats, O-ring grooves, flange bolt patterns, chamfers, and socket lead-ins. Preview & Test Tools Use section views, test pieces, and Debug mode to inspect geometry and dimensions.   ℹ️ Notes Some controls apply only to specific interfaces. Rectangular dimensions require rectangular ends, thread settings require threaded ends, and O-ring grooves support round sockets and flange faces.   The generator validates many incompatible dimensions and clearances. Still inspect short transitions, large offsets, and tight bends in Section View or your slicer. Use Debug to diagnose geometry.   For critical fits, print an End A Test or End B Test first and tune Fit Clearance for your printer and material. Use Print End to choose which end sits on the build plate.   For additional guidance and troubleshooting, see the Frequently Asked Questions attached to this post.   Feedback and examples of what you create are always welcome! 📜 Maker Scripts Boost MeYour support helps fuel continued updates, new features, and new models.
