Damn Filament won't stick no matter what!

Also if you're using blue tape - DON'T get it from the dollar store. I'm a pound shop junky - but even I have to use the expensive painters tape.
You'll need to get the genuine stuff - euther duck brand or 3m. It's thicker, wax impregnated and pla sticks to it at 50c to the point that you only get the print off by removing the tape with it.

As far as that print goes - you're going to need a whole helluva lot of support - so probably best to print with a raft for the support to attach to. Also if you printed it upside down, you'd need less support - but still probably best to use raft.

That whole model is just not designed by someone who's ever 3d printed anything.
