K'nex Screamin' Serpent Chain Start

I've always struggled with how to start the chain tube on the K'nex Screamin' Serpent based roller coasters.  I've been doing a lot of custom track designs recently and have needed this type of piece to help get the chain started over the first crosstie of tubing.

The idea is simple really, the piece slips into the crosstie and fits around the start tubing for the chain.  Because of the curve it allows the chain to easily glide over this piece.   

Really happy with how it turned out, it is one of those rare designs that it worked on the first print.
