This thing is based on BishobMarthen's idea.
This steak is a key chain to carry around your favourite flexi rex, it's a tight fit so you won't lose your rex.
The Steak is 8mm high if you want to have the fat in a different colour (like the shown steak) you should change the colour in the 8.1mm layer.
The real deal would be a TPU or TPE Steak, so you can fight with your rex for it :D
Have fun building your own.
