I really like the open hinge concept and I took it a couple steps further.
Here are two added features:

1 - Keeps the door open; when the door if fully open, slide to the right to lock the door into the open position
2 - Hinge only separates @ 30 degrees from vertical. The hinge will not let go of the door unless the door is almost all the way open. This means through most of the motion of opening, the door will stay where it is. Also the door will not come off while in the fully opened and locked position. Makes one-handed opening much easier because the door doesn't accidentally separate.

Note: The best orientation to print, for me, is as shown in the 3rd photo of the orange models.

I printed in PETG with 100 % infill. I'm sure you can get away with less infill. I also used supports but it seems they were not necessarily needed.

Beautiful functional and elegant design - thanks for sharing!

Very glad you like this!

This is a great hinge.

Tip of the hat to you, my friend.

This is the best. Thank you so much for creating this remix. Locking in the open position is awesome. Sometimes I argue with it to get it completely unhitched, but it has never come off inadvertently. You get top votes for a totally elegant solution to a problem I didn't even know could be solved this way.

Very kind of you - thanks!
I find it easiest to unhinge with a gentle pulling motion while manipulating the door from the bottom edge, i.e. the edge farthest from the hinges.
In the beginning I also struggled to unhinge the door, but I found hand placement to be key. The closer I was to the hinge the more struggle and vice versa.

Great remix! I really like the idea that you can lock it in the open position. I didn't even think about putting flats on the hinge pin.

Cool, thanks for the comment!
