looks like this kickstarter has been funded. Pretty cool - us$35 for a brand new c64c case... manufactured from the original moulds, and us$10 international shipping.
Note that the photo's are actually 3D rendered images (which is the only reason I spotted this campaign) but its a cool option for replacing old cases. Its a pity the breadbin wasn't found by this guy as well, but nice stuff... limited moulds of beige and transparent can be added to the order, otherwise they will come in white, red and blue...
