I have had a PRUSA i3-MK3S fo a couple of years now. I bought the kit and put it together. They had the power supply wired wrong so it took a couple of weeks to get it going but it has been problem free since. I have printed in petg, abs and pla. I design things in Fusion 360. I use it for all kinds of things woodworking related and not. I also print star wars and ailens stuff for my wife that I find on Thingiverse. My longest print was about 26 hours. My latest thing are some 1/16" spacers to put op some mosaic tile backsplash. The store bought "+" ones don't work well.
