I made these to fasten/support things in my garden. Soccer goals, plant supports e.t.c.
I printed them in Prusament PC, witch seems to be able to take considerable beating. But UV resistance might be lacking. PETG is also an option.
Free CAD model files are included, mess with them at your own risk.
Disclaimer: Printing these in wood filament and using as weapon against vampires is not recommended.
