About this 3D model

build your own drive chain with the parametric chain.scad script or just use one of the exampels (test_chain.scad) __example 1__ - easy assembly / disassembly but not really strong - 35° overhang and 0.4mm gap make the print easy __example 2__ - same like example 1 but with a snap_fit hinge (stronger) __example 3__ - real strong chain but can not be decomposed __example 4__ - same like example 3 but the first chain-link have a snap_fit hinge __example 5__ - another easy assembly / disassembly chain hinge - this chain is bigger then the other examples __example gear 1__ - fits on example 1-4 - 9 teeth - M4 hex_nut hole __example gear 2__ - fits on example 1-4 - 20 teeth - M8 hex_nut hole __example gear 3__ - fits on example 1-4 - 8 teeth - 5mm motor mount (need a M3 nut + screw to fix) __example gear 4__ - fits on example 5 - 15 teeth - M6 hex_nut hole
