Don't have pictures of the printed model and can't make them either as I printed these for my aunt. They fit and work perfectly well with all the existing hardware.

printed them with Petg and they've worked for about a year already, original replacement parts used to be available for 15 dollars a clip, but aren't available anymore and were way too expensive (these will set you back about 2 dollars for 30, at least that's what they cost me a year ago)
