Lotti Karotti (Funny Bunny) Replacement Arrow

Replacement arrow for the Ravensburger board game Lotti Karotti, sold as Funny Bunny outside the German market. 

It sits on the pin with a 4.2 mm hole and has a small upright fin at the tail so kids can grab it and turn it.

I printed it on a Snapmaker U1 in Sunlu PLA Basic and it fits our board as is.

The model is 48.8 x 15 x 7.3 mm and the plate is 1.3 mm thick.

If your board or pin differs, open the .scad file in OpenSCAD and change the values in the parameter section. All dimensions are in mm:

• hole_diameter is the pin diameter plus about 0.2 mm clearance. Default 4.2.

• total_length, head_width and thickness set the arrow body.

• tail_style switches between fletching, notch and flat.

• fin turns the grip fin on or off.

• mount_style = "peg" swaps the hole for a peg if your board has a socket instead of a pin.

The STL is the default configuration.

Print settings

• PLA, 0.4 mm nozzle

• 0.12 mm layer height

• 3 walls, 100 % infill, which is effectively solid at this size

• No supports, print flat as exported

The included 3MF is my Snapmaker U1 project with these settings.
