Hyundai i30 (2017) cup holder replacement of original cup holders in interior.
Three of them was missing so i just printed new ones:)
Originally i thought that i will use some metal spring inside of holder shells but i did not found them in local hobby store so i have printed some kind of spring as well.
Looks good and probably it is working as well(do not tried as i did not have any cup to test:)
Easy print without any supports.
Fusion360 file included.
