This is a mount to go on the side of a bunk bed created to allow for a place to put phone and drink but the mounting system is basic and can just be reused. I found it odd that this type of mounting system was not more available and copyable. You can adjust the height on both sides but the width and length need to remain or you will need to readjust the holes. The Idea here is to help the next person. To create this type of connector just create a rectangle then slide a triangle into it and cut each side at the same depth. Then copy that and make it a hole on the other side. This is fairly basic. The hole needs to be .5 width and length bigger than the male side almost regardless of the size of the male side. I think this is due to PLA shrinking though. This model is already set up that way and slides nicely without being sloppy. Feel free to steal this and not give credit to me I don't mind at all. You can get the model on Tinkercad where I created it but the smoothing of the edges does make it run slowly. The Gimbal is a remix. I mean to be fair is just a copy of cut and paste of https://www.printables.com/@mobiobi drink gimbal. So please if you want to thank someone thank him boost him whatever. https://www.printables.com/model/129329-universal-travel-coffee-gimbal It is pretty cool just print and go I really like print in place movable things like this gimbal. It works perfectly with a stanley cup. Or you can print this insert https://www.printables.com/model/151413-cup-insert-for-universal-travel-coffee-gimbal The models are setup to have supports where needed and not where not. The mount that connects to the 1by4 needs supports and the phone holder needs supports the rest of them do not.
