Its very badly designed, whoever made it didnt understand the equations involved. Its very badly lopsided; makes for a violent release (inaccurate). The connectors are not properly placed, nor are they properly spaced. Cams have to be tuned for your bow. If you dont understand geometry, trig and force equations, please dont release stuff like this. Some idiot is gonna download it and think you knew what you were doing and get injured. Even with carbon fiber PLA, this thing is dangerous. I just ran it through diagnostics in CAD, no bueno my friend.... It was a valiant attempt, but if youre new to this, i recommend you copy existing designs and go from there, theyre patented for a reason bud. This is no "toy", please use your head when designing something that has the potential to seriously injure someone. And no, just because it fits into a bow, doesnt mean it works. lol.... Its not that simple.
See how theres cuts in weird spots on the original? Those are there for a reason, you have to balance it. Use a material density calculator and set your displacement geometry accordingly. That will stop the violent releases.

How big is this thing supposed to be? When I load it into slicer it either comes out way to big in inches, feet, or meters. And when I use Milimeters it comes out less than one centimeter. Would you please let me know?

Thanks

Hello, the CAM is designed to be 120mm. If you open it into ReplicatorG and scale by 1.2 then this will be the correct size to go into a Triangle compound bow. If you want it to fit it to a Hoyt Compound Bow then scale it to 1.55 and this will be the right size.
