Huge fan of Hero's Hoard goodies their work is mostly 25/28mm though. As I play in 15mm I made up these doors so their dungeon kit is readily adapted.
Just print the normal tiles with connectors and when a door is needed use this one.
The steps were needed because shrinking the door evidently made it too short to reach the floor and it looked "off". This is the best solution I could come up with.
Note that the Angel Door is printed in two parts - door (open or closed) and base.
They printed well for me, I put a run on my printer bed fitting as many I could one evening and woke to enough doors to last me for a while!

If you don't know Hero's Hoard - go check their website out I have a lot of their stuff and it's great to support companies that give so much away free anyway (barbarian huts, stone buildings and their tavern interiors are must-haves. Oh and the caravans. Oh and the elf town. Oh and the abysal...nevermind. You get the gist!)
