GuerillaBeam parametric extension tube

These extension tubes feature the 53x3mm 90° threads found on all screw-mounted GuerillaBeam parts. Their obvious use is for creating additional distance between projector parts.

Their real purpose is to help you create your own lens adapters, light adapters, and/or accessories.
You can remix the OpenJSCAD and/or recombine parts of it in your favourite 3d modeller.
Some experience is required, but reading this, you can probably do it, and I'm always glad to help.

Only for convenience I've included some (slightly older) STL files for common lengths.
Instead, please use this OpenJSCAD for making custom lengths or edits.
OpenJSCAD caveats:

• Set "print quality" option before exporting
• the JSCAD code lives only in your browser
  • don't press F5 (your changes will be lost on page reload)
  • save your code to some safe place, e.g. a .jscad file on your computer!
