/diy/ - Do It Yourself

I picked up an ender 3 and I've been fiddling with it for a few weeks now. I'm learning to use thinkercad and doing various small adjustments and test prints. Tomorrow I'm looking at changing my nozzle down to a 0.2 for printing wargaming terrain and model parts. I've shifted my print speed down and I expect to get okay results but I'm curious what I could do to improve them further.

I want to print a town for a display board and add on parts for gunpla. I know they will need sanding and possibly filler spray on the flatter surfaces and I'm okay with that. Just fishing for any tips I wouldn't. Naturally run across.

Pic is a print I did a few days ago to test filler primer and painted up.
