Creality K1/Max 270deg Door Hinges

thingiverse

These are totally re-designed models from the original source design by EricMoya. I found his did not match the screw holes well, nor the case bevels at the corner, plus the way the bolts used as pins would fit the parts optimally.Choose the Fixed Door type set - if you want a fixed door.Choose the Removable Door type set(s) - if you want a Removable Door. There are two types of Removable Door hinge mounts - one set is heftier/stronger. Maybe you like a bit less material and "clunkiness" in looks, so the "non Stronger" type should still be totally fine.Glue the A & B Hinge mount parts together with Superglue. There are 2mm locating pins if you want to use those for alignment, but you could also just use the screw holes - with screws through those - for alignment.... or even just visual can do a fine result anyway.They were made in halves so that the printing quality can be optimal ! No supports and no overhang 'blahness'.For the Hinge Pins, use 3mm bolts. The Fixed Door type can use 4x 30mm or 40mm - but it will work fine with only two from above (easier to fit).The Removable Door type are better with longer bolts, so 40mm to 50mm. Probably nicer if they come to the top of the Door Arm almost.Infill would be better to be 100% because of the lay of the layers, meaning the hinge 'humps' could break off at a layer. Thus more Infill means each layer has a lot more strength in their 'joins'. But really, even 30% region Infill would probably be strong enough, though that is hard to test and prove so 100% is safer(safest)!
