A remix of Emmett Lalish's venerable heart gears, this adds spots to the center block and the inside of the gears to aid in assembly.
When assembling the gear heart it can be difficult to tell some of the pieces apart or determine where they go; the two smallest gears in particular are nearly identical and are easily confused. To address this, each gear has from one to four small dots surrounding the pin hole; big and small gears that are opposite each other have the same number of spots.
The revised SCAD file is included, as well as STLs for all three gear ratios in the original: 1:2, 2:3 and 5:6.
