Tom's simple PRINTinZ Zebra Plate clip (Printrbot Simple Metal)

If you use adhesive Zebra Plate from PRINTinZ (or their previous pinkish plate like me), these clips are useful to quickly mount the plate to 6mm heated bed – like the original one from Printrbot Simple Metal. 

EDIT: New Zebra plate (black&white) is here and it's thicker than the original (pinkish) one. So if you have same (b&w) version, please change model scale before slicing. I will eventually resize original model.
