QIDI X-Max 3 Door Hold Open Over Hinge

For the QIDI X-Max 3.  This bracket goes over the top of the door hinge as in the first photo.  It is a tight fit - prop the door open about 90 degrees and slide the bracket opening over the thinnest part of the hinge and rock it gently in to place.  I printed it out of PETG - suggest ASA or harder and make a spare! :-) Update, did it in ASA and it's held up well - also chamber stays at 30C or below with the top also cracked open.

Once you have it vertical, rock it forward until it fits flush up against the printer case on the outside of the door.  Wiggle it to get the recess for the hinge pin top to fit into the slot cut out in the bottom of the top of the bracket.  Due to all the weird angles here there are thin parts - move slowly/carefully.  Once you've got it on the first time it becomes intuitive.  I used to have a stand off that fit on the bottom frame and poked out to hold the door open.  it was easier but less stable for me.  

I expanded the part of this (the more slender vertical piece) to be fatter to hit the inside of the door frame and create a surface the thin back part of the door fits against to get the 30 degrees of opening.  As you know, the X-MAX 3 DANCES while printing, and I have HULA feet under it so the door will bounce around and this hinge bracket method is more stable for me anyway.  That movement also made my stand off on the bottom door frame less stable to stay on.

Good luck, please post a make if you try it and it works for you! It was done in TinkerCad so no STEP file to post, but feel free to work it further and go check out the original on Thingiverse as linked here to see where the idea came from and use his if you like holding the door all the way open, 180 degrees.  His solution is shown in picture 4 as well as on the Thingiverse page, of course.
