I haven't printed the whole engine yet so fitment is not guaranteed. Models may get updated down the Line
~July 15th 2025
After scrolling through the comment section of Kocyns Wankel Engine I stumbled upon a commenter who modeled themselves some Apex Seals but didn't release the model publicly.
So I modeled some myself.
The Last Picture is supposed to show the overlap/extension between the spring and the basic seal
Print the Rotors first, then a Test Piece to check for clearances, as demonstrated here

Print Settings:
Layer Height: 0.20mm
Walls: 3
Top/Bottom Layers: 3
Elephants Foot Compensation : 0.25 (optional for clearance)
Material: PETG or similar toughness (bendable)
To work it needs to be round or at least square. Adjust your Z-Offset and First Layer Width if necessary
Printed on an Elegoo Centauri Carbon
