Cat carrier locking tabs

Just a simple recreation of the existing tabs, recommend printing in PETG or ABS/ASA for strength, otherwise PLA works but may want to raise the printing temp to make sure layers adhere well. 

Can print standing up on the flat bottom, or lay on the flat plane on the tab at the angle so you get a little more strength. 

Dimensions are all in mm, had used inch measurements I was given but designed in mm using Solidworks
