You attach the bands by pushing a looped end into the slot from the side and locking it with a piece of filament through the center of the loop.
Print in 0.15mm with 5 perimeters and 13 top/bottom layers.
I used different infill percentages for the different parts of the slingshot but it's up to you.
You need those 5 perimeters if you want to sand it after printing which I HIGHLY recommend!
If you like you can print two eyes in TPU and push them into the hole from both sides.
The opening in the eye is designed to hold a 8mm steel ball.
Here's a tutorial for attaching rolled up bands:
