Instructions on how to use can be found here: https://www.thingiverse.com/thing:11643 The original design linked above was made for a big cage which is not typical. This cage is made for a more common 5" diameter fusor chamber. (Optimal cages are 20% the diameter of the chamber, so this 1" diameter cage is perfect for 5" fusors). So if u have a 5" chamber this is for you! The original design also had bolt holes that were really small. I made these for more common 4mm OD bolts like the ones used in vex robotics. A 1/4" vex bolt is perfect for this. I made the holes small enough that you kinda "tapp" threads into the plastic as you screw the bolt in, so it self tightens and there is no need for nuts. Just screw through until tight.
