Trip Wire Perimeter Alarm for Camping Tent

If you, like me, are afraid to sleep in a tent, then you will definitely need this alarmed perimeter!

You can also use it to play pranks on your friends!

For assembly you only need m3 nuts and screws, glue and a sewing needle to cut to 25mm.

printed with a height of 0.2 and 10% filling, petg, I recommend a 5mm brim on the cylinder.
