I have been 3D printing since about 2012, using both filament and resin printers. I have built several of my own and have had to learn how to troubleshoot many issues (the hardware back then was not as nice as it is today!). I started modeling my own models several years ago, and I am a self-taught Fusion 360 user, so go easy if there are some engineering issues in my models that don't make sense! ;-)
