Keep in mind the time involved in printing your own stuff. I have a Creality ender 3 that's been running pretty much 24 hours non-stop for 3 days to print a Dunlop tire bridge to go over a Carrera slot car track. Somewhere around the middle of the bridge printing I found one online for $20 plus shipping. I don't know about resin printers but filament printers are slow.
