I'm (*personally*) not the biggest fan of cup holders in cars - but I know some of you quite like this feature.. that being said - I stumbled across this unique project and thought it was worth a share - (I'm not taking any of the credit for it, have not carried this out before and cannot help with any technical questions more than are already answered in the link) - but thought it might give some of you some inspiration for a unique/worthwhile mod?:
