About this 3D model

My son and I spend a lot of time building TrackMaster tracks and I was disappointed that we couldn't have two tracks on top of each other. So I came up with this solution. In the original I put diamond cutouts in it thinking that would cut down on time and materials. I was very wrong. When I print two of these with the diamond pattern it takes about 9.5 hours and 92g of filament. But doing two solid risers will only take 6 hours and use 70g of filament. I'm leaving the old version up just in case people like the looks of it better.
