Disc golf cart accessories holder

I made this for my dynamic disc backpack cart top bar and I think it can be used for the zuca carts as well because they make DD carts not sure about other carts but the bar would have to be under 23mm outside diameter. the size of project is under 120x120mm for monoprice select mini.
I recommend using at least 25% infill and thicker walls for pla
can be used to hold scorecards, smart phone, pencils, pens, markers, towel in front , 2 D rings for bag tags and things
for my setup it take 24hr
