Cat Carry-Case Lock

This STL file is for a lock of a certain brand of cat carry case (see pictures). The top 2 thingies are the original ones, of which the left one is the one that broke.

I designed new items in OpenSCAD and 3D printed one which you can see at the bottom of the image.

Best to fill it in entirely so it's stronger. Ideal would probably be to print this with ABS but I did it with PLA which is just strong enough. The part isn't weight bearing so PLA will probably be fine (the case is held together with larger brackets).
