This drinkholder is made out of two seperate pieces that are meant to be held together with countersunk screws. I used brass inserts for mounting the screws. You can also screw them direct into the plastic or even glue them together.
I sliced the big plate with variable layer height because of the big fillets and so you dont't need supports. If you are an ablsolute madman like me then you can also print the plate standing on the side. Just saying this is a terrible idea and will most likely leed to some lost hours of sleep, but it is possible. Even when possible means that the whole thing only sticks to the build plate right in the middle and the edges rising about 10mm ;D.
The holders themself are also sliced with variable layer height, but only on top for a fine fillet and no edges.
Hope the plate is usable for some of you. For everyone else you might need to design a plate for your needs.
