to help my girlfriend clean up her car i created a holder for 6 cds, which she can easily put in the tray fold of her car.
if you print this item with abs, you should look for very good settings because of warping (printend @ 47 room temperature degree and still had small warping issues). not sure if petg maybe has problems with hot car temperatures in summer.
the rubber is printend with flexfilament to fix the item in place. i uploaded the designspark mechanical files if you want to edit the object for example to reduce warping. she drives a 2010 peugeot 207. i don't know if the dimensions of the tray fold changed during the years.
