Duplo slide

Found 2 Duplo slides here, but none seem to resemble the brilliance of the original I saw on pictures online: that you can connect it into an endless slide. I used the models to get the connector positions right, but redesigned everything from scratch, with slanted inner walls for the connector bottoms to improve the fit even on bad prints or when aging.

This model is by nature in need of a lot of support, which was adding about 50% or more in material use. I prefer to design my own, so I waste less material and have less cleaning to do. I add both versions, with and without my own support, for everyone to choose their preference.
