Magnetic Fishing Game for Kids

Instructions:

• Print without support
• Some thin rope to attach the hook to the fishing rod
• Magnets 10MM X5MM round for the hooks and the box (4pcs total)
  but smaller magnets will also work! Just put some tape on them.
• M6 nuts for the lid (2Xpcs) but any metal is good if it fits! 
  Dimensions: 5 mm height, diameter 10 mm
• If desired: Small piece of metal wire for reinforcing the joints on the box
• For the fish, use a washer M10 (10pcs)  

Tip: use some glue on the magnets when inserting them, and wait a minute. Otherwise, the magnets could pop up on the heat block screw!

In the new version all the washers, bolts and magnets are inside the print!
Tank you @BikeCyclist  for this idea.
when slicing the case, hook and fish; place a pauze mid print:

For attaching the rope to the hook, a pushpin could help.  Make a small knot and pull the rope back into the hole.
