Blowpipe laser sight mount

I bought an aluminium pipe with 16mm inner diameter for shooting paper darts. To help me aim i bought a [cheap laser sight from China](https://www.banggood.com/532nm-5mW-Red-Dot-Laser-Sight-Scope-Tactical-Black-with-Adjustable-Rail-Mount-p-1171352.html?p=6E2214592974201405G7) and created a mount in [OpenSCAD](https://www.openscad.org/). Calibrating is easily done by looking through the tube at the desired distance and turning the screws on the laser until you see the red dot in the middle of the tube.
The laser aim works remarkably well, i shot a wasp from 5m (not in the habit of killing insects, i really didn't expect it to hit). Since the model is done in OpenSCAD,it's easy to adopt any parameters should you want to. I would advise to print in PETG if your printer supports it, since it's strong and flexible.
