Toys for boys. Old boys use computers, small boys need other toys If You remember or use this design Toys for boys-ships/ anchor+Kenter shackle+swivel - https://www.thingiverse.com/thing:4910559 (code included now) one thing was missing - chain. Of course, You can buy some, but not anchor cable/chain common link with crossbar, nor missing link that size. So.. here are ordinary chain link with switch to add crossbar for anchor cable/chain common link and switch to create missing link for both links. Missing link is used to connect 2 lengths of chain links. There is no such thing for anchor chain in reality (only Kenter shackle) but for toy purpose it could be useful. Rendering rotate extruded shapes in OpenScad is... well, time consuming. I made stl of 1 and 2 links, then use FreeCad to join them. Step by step on pictures. print 2 pieces with pins and join - anchor missing link needs additional pin to join crossbar (or use piece without pins and add pins on Your own). link(wire) diameter, outer diameter and link length are adjustable- every change in link diameter require new set of pins.
