WARNING!!!! WARNING!!!! WARNING!!!!!
experiment was a failure in my book but others found it worked so ill leave it up. fixed by replacing snap with pin
my printer is down, so I couldn't prove this one works....
that said pretty sure it will be easy print....and link.... also pretty sure it will need to be warmed up in hot water to prevent cracking while assembling.
If you choose to print this suggest 5 of them to see how they work... please let me know.
should be close to 120mm wide 6.25mm snap....7mm holes
added modded version will positively need very hot water to link has better geometry, left other in case someone wishes to fiddle with it
another mod made... now a little more tolerance for fit, had issues getting links together so gave it a little more room note that the file names are progressive and moda is newer design than mod and if I adjust it again it would be modb and so on
ok I leaving this to someone else....
redesigned with 3mm pin for the hinge....works fine that way
