I've been into 3d design and printing recently, I've been building a car from 1993 which means I'm missing some bits and some plastic bits have broken etc so I thought I'd start designing the replacements. I first got a 3d printer a few years ago, it was a ender 3 which is one of the most popular 3d printers, I called it Karen because it was painful to use and eventually I gave up on it as wanted too much attention and upgrades to keep it going.
I now have a Bambu P1S which has been brilliant and would happily print anything I threw at it, including ABS and ASA which are the best filaments for car parts etc
I've been using Fusion 360 for my designing and have made quite a few models which have been pretty precise and fitted well, I've setup a website for all things RX7 which has links to my Cults and Printables pages at the bottom.
