Fish Ruler

I find the commercial fish measurement rulers are too skinny to use attached to the rail of the boat so I designed my own version of it with a wider footprint to make it easier to hold the fish down. I have uploaded a two piece version that can be printed on any Max printer and a one piece version that can be printed on a belt printer like the Creality CR-30. No supports are needed for this and I recommend ABS or ASA filament as direct exposure t sunlight can be detrimental to other filaments.
