This is a piece designed to fit on a 1 DIN space of a car. The measure should fit lots of cars, but the measures were taken from the original TAPE unit of a Mazda Miata NB1 '99, so it will fit perfectly on a NB1-NB2 MX5 or Miata, but the design has been successfully tested on a Citroën Saxo and should fit many more cars as the measures were done bearing in mind that it should fit on a single DIN space. Right now I got a previous version of the design printed, so I don't have photos of this design printed in real life, but according to the measures, it should work fine!
EDIT (15-apr-2019): I've uploaded a new version of the thing because I printed it and some parts were too thin that they broke. The angles of the holders were too small and they didn´t do their work properly, so I've redesigned some bits. I can't reprint the piece to test it, but please, report if the piece clicks into the DIN space on your car if you print it, and send pictures!!
