This shroud designed to work with the Saturnus Nerf Ballistic Chronograph Rechargeable v7 by LegoDEI (https://www.etsy.com/listing/1149863739/saturnus-nerf-ballistic-chronograph) with the tripod mount screw option.
Just slip your chrono inside and thread the tripod through both. Notch goes in front, but the hole for the USB recharge port should make it obvious.
Useful if you want to chrono your darts outside, as sunlight can interfere with the IR sensors.
Print at any layer height, .3 draft works great, with the edge with the little notch facing the build plate. No supports needed.
The author marked this model as their own original creation.
