This is a very old model I created in 2016 and imported from my Thingyverse profile (https://www.thingiverse.com/TheZerschmetterling). Maybe some links are broken or not up to date. If you have any questions do not hesistate to ask.
This is the modified camera mount using a Polaroid Cube on a Shendrones Corgi
Edit 24.06.2016: Just updated the print files. Each part is 0.75mm thicker then before to fit better with the elastic material the Cube provides! Also the hole on the back got a 0.5mm push to the front for a better fit.
