Printable fasteners in any size: metric bolts with hex or thumb heads, matching nuts, washers and threaded rods. ISO presets M3 to M24, custom pitch, left-hand option.
Free and without an account: type the numbers, watch the live preview, download STL and 3MF files that Bambu Studio, OrcaSlicer and PrusaSlicer open directly. Looking for a ready-made size? The model library has 651 of them, each with its dimensions already filled in.
The ISO presets follow the metric standard, so a printed M8 bolt threads into a steel M8 nut. Printed threads are a little slower to start; use the clearance setting if a pair binds.
Strong enough for jigs, furniture, knobs and anything you would tighten by hand. They are not a replacement for steel hardware in structural or safety-critical joints.
Yes. Beyond the ISO presets you can type any diameter and pitch, and the matching nut and rod come out of the same settings.
Your exact configuration is attached automatically, so the bug can be reproduced one-to-one. No account needed.
The machine that generates the models seems to be down or restarting. Your settings are safe in this tab: nothing is lost. Wait a moment and try again.
