I got the casing vector files from another post and converted them a couple of times to get a useful file type and uploaded the objects to tinkercad.com
I have so far only printed one case that is caution stripe yellow and black and has worked out quite well.
These prints were done in a yellow part and black part and then glued together.
All printed on an Anet A8 that has a print bed 220mm x 220mm
I have made the tinkercad files public:
