Empty Spool Magnet Fishing Reel

thingiverse

You will need - Empty 1KG filament spool (spool holder section has a 1.7 inch diameter so the hole must be larger than that) I used a Prusa 1kg roll, the one that comes with the printer as I figured many people will have one. - Two washers .75"OD .25"ID .08 thickness - Two washers .55-.6"OD .25"ID thickness is not too important here, not too thick though - One 1/4-20 bolt between 1 inch and 1.3 inches long - Two M3 screws(bolts) with corresponding nuts - .28-.3 drill bit - .150 drill bit The larger washers get sunk into the "interior" and "exterior" pieces that go into the side of the spool making sure it's metal on metal rather than plastic on plastic. The two smaller washers go against the 1/4-20 bolt cap and the handle end see photos for clarification. Everything else goes together exactly how it looks nice and easy. I don't recommend using this if you hook something large I printed it in PETG and seems very sturdy, I have a 500lb magnet on the end, it will not handle something anywhere near that heavy. (Edit: Added non-catch version of the interior handle piece. file is "magnet fishing spool interior" all lower case.)
