Frequently Asked Questions
Yes. The 3D Print Standoffs / Spacers Generator is 100% free with no limits, no watermarks, and no trial period. Generate and download as many files as you want, free forever.
Free cylindrical standoff and spacer generator with custom OD, ID, and length. Adjust the settings, preview your design in real time, and download a ready-to-make file in seconds.
It exports STL files for 3D printing, and multi-colour 3MF files where multiple parts or colours are involved. Files are generated instantly in your browser.
3D printers via slicers such as Bambu Studio, PrusaSlicer, OrcaSlicer, and Cura, with 3MF files carrying colour data for multi-colour prints.
You can use PLA, PETG, ABS, TPU, and any filament your printer supports for 3D printing. The generated files are standard formats compatible with any material your machine can handle.

Open the 3D Print Standoffs / Spacers Generator guideHow To Use
Choose whether the spacer should have an internal thread or a plain bore.
If threaded is enabled, pick an M-size preset to match the fastener you want to pair with.
Set outer diameter, inner diameter, and spacer length based on your screw and stack-up height.
Switch units to mm or inches and adjust values directly in the settings panel.
Use the sticky preview to check wall thickness and proportions while editing.
Export STL or 3MF and run a quick test print to verify fit on your hardware.
About
This free 3D print standoff and spacer generator creates custom cylindrical spacers for electronics, enclosure assemblies, panel stand-offs, PCB mounting, stack-up testing, and general hardware prototyping. You can generate either a plain-bore spacer or a threaded standoff, then tune the inner diameter, outer diameter, and overall length to match your screws, boards, and clearance requirements.
Printable spacers are useful when you need an odd length that standard hardware suppliers do not stock, or when you want to validate board spacing and fastener fit before ordering metal parts. Export STL or 3MF files for PrusaSlicer, Bambu Studio, Cura, or OrcaSlicer and iterate custom spacer dimensions quickly for maker, repair, and engineering workflows.
