Hose barb for pool pump

Needed an adapter for my pool pump adapter and didn't want to drive to get one so I made one up in tinkercad. I'm a novice at 3d design so it might not be perfect, this part is to adapt a pump from 2-1/2 threaded inlet to 1-1/4 hose using a slip on threaded collar. This is my first actual original design so any suggestions are welcome, I. The process of printing will update on functionality once done.

Update1
print was successful was set to 100% infill (i didn't want the pressure of the pump breaking it)and was even strong enough to not break after tightening the hose clamp with my impact drill, unfortunately i didn't think to take any pictures after printing before i put it on the pump. it also turns out that i needed it to be 1-1/2" not 1-1/4" so i have a small leak due to the hose being just big enough to let some water through. edited the original one and made it 1-1/2" and added it to here as well, will be printing that one today also the first one was a 13hr print due to it
