Hi Ronald! Welcome to the site. I have been 3D printing for almost a year now and, trust me, you’ll love it. A really good place to start designing is Tinkercad. [www.tinkercad.com] There’s an intro tutorial and a really simple learning curve. Check out the Youtube channel ‘CHEP Filament Friday’ for some great videos about 3D printing with many instructional designing videos using Tinkercad. Let me know if you have any other questions, or if there is anything else I can do.
