More printable print in place Ohmu

This is my remix of printinplace flexible support structure free Ohmu.

I printed mine with a 0.8mm nozzle on a revo modded cr10 mini from PETG.

The raft layer version (0.25mm high raft) is optional and will reduce flexibility but also allows for the print to actually finish in case a segment lifts up from the bed (very likely) and on a larger print (20+ cm, in length) , i do recommend that version.

Have fun printing :D
