No supports needed if to print 0.15-0.1 layer height.
I recommend to print both of the plastic parts from PETG plastic, but you are free to chose other plastics as well. I prefer white color for the bottom part and some dark (grey, dark green, or grey-blue) for the top of the shark. But You are free to chose any colors you like.
The bottom part of the shark has 2 slots for cylindrical magnerts (10 mm diameter, 5 mm height) on the opener side, so the opener can be easily placed on the fridge door or smth.
To fix the magnets in the slots, please use superglue, hot glue or similar (I prefer super glue). The same way you can fix both of the printed parts of the bottle opener.
The magnets will alow you to always keep this opener on the fridge door and press some paper memos on it, if u need that sometimes (which someone might found quite useful). It's also quite handful to use magnets on the bottom of the opener to catch the bottle caps :))
If You don't want to place magnets, though, you can just skip the step with magnets and keep the opener body with open slots for magnets, OR you can print those small cylinders from other colour of plastic and glue them instead. (for that please find "insertion_10x5mm.stl" file) from the original model: https://www.printables.com/model/998039-cute-bottle-shark-opener-bottle-shark-tu-tu-tu-tu#preview.VaGnw
The metal part of the openner (4x1.8 mm or 4x2.8mm) can be found on Aliepress, Taobao or Amazon:
You'll also need two M3x5 or M3x6 mm screws and two threaded heat inserts for plastic, as shown on the picture:
