I understand that. I’ve tried ABS but I couldn’t manage to get those big prints out of the machine without warping or shrinking. This way the parts wouldn’t fit into each other anymore. So with a printer without a housing like the Ender 3 its almost impossible . Plus printing without infill saved me a lot of time. That’s why I came up with the epoxy filler. it worked really well for me. Cheers 🙌
