Here is the result of my efforts in making a simple plastic bottle opener.
After several attempts, what you see here is the best I have managed to achieve in terms of size and stiffness. In fact it was printed in PETG because all the other tests I did using PLA ended up in the dustbin due to breaking under stress.
The coin is a 1€ cent, do not know if other coins fit.
So print the object in PETG only 100% infill.
