Runner, Gates and Spin trap (surge trap) system - extendable version

This is based on the spin trap (surge trap) by Bob Puhaka that was discussed/given to SWDweeb (Perry) off of youtube.

I made it extenable to fit flasks of any size, it uses 3mm pins to connect everything together. (see my flask project for details on the pins) https://www.thingiverse.com/thing:4033453

this is my version (JulianHG off youtube) based on watching SWDweebs :)

The intent is to trap the initial surge in the circular trap. Without the trap, the surge is redirected back into the flow of metal. Just one more way to reduce porosity.

The trap should also be used with a gate that is perpendicular to the runner.
