Recently my son has had this facination about sharks, so when he wanted a shark-themed birthday his mother and i decided to make custom seating arrangement cards that all of his friends could take with them when they left the party.
When scouring the internet for a suitable shark 3d model i came across this model on thingiverse by the user XYZWorkshop.

Since i recently got a Form 1+ 3d printer i decided to use this to print the sharks in gray and clear colors.
I modified the model so that each kid got their name on the side of the shark. The kids really loved them:)
