why don't you just buy a quality machine that will work correctly out of the box and allow you to learn all the things you need to learn about designing components that will be 3d printed and actually printing them, before you redesign a franken junker. Drop that $2+K and get a solid well designed machine that does everything you need out of the box but is not as large as you "Think" you need.. Just my 2 cents worth after seeing sooo many people fighting with inferior hardware rather than designing and fabricating parts. Look at Prosumer products and stay away from Creality crap. I am sure you will ignore me, but later on when you are still not getting what you want and you are frustrated, remember I warned you...
