Deck Cup Holder

Was looking for a cup holder for my Deck around my pool. Made these to be mounted on the the rail posts (2 x 4's or 4 x 4's) should fit almost any glass/cup, Also mounts at a slight angle to let rain water to flow out of cup holder. Uses 3 deck screws to secure it to the post, about 4 x 30mm (1 inch drywall screws work as well)

I printed in PETG and yes my settings are not perfect, but it works for me :-)
