I took the extended tapered Sprue that Pauls Garage made and split it in half and made a pin for it in case you want to cast it.

I also recreated a surge trap and and riser that I saw on Swdweebs youtube channel. The Sprue should theoretically fit in a small hole on the surge trap.

I will also probably make some simple gates and if they work I might put them on here.

I uploaded the Sprue as one whole part instead of two halves because the two sides are not exactly the same size.
