Issues with Printing gregs wade extruder? (with pictures)

Hi all,

I'm trying to print an extruder for my next printer build. I'm using the following STL file

link to the extruder on thingiverse

I want to print at 0.3mm layer height but I have problems with the support block and the bridging for closing the bearing slot (see picture). I sliced with slic3r and normally I can bridge great distances. I killed the print because it didn't seem right...

Do I need to print this part with 0.2mm layer height? Or do I need to enable support material in Slic3r. I prefer to ask this because my spool of blue PLA is almost finished and still need to print the extruder with the same color.

EDIT: now I realise that these "issues" may be part of the cleanup but I do not know for sure since I never printed this extruder. So if you ever printed the body of a wades type extruder please report if this stringing is normal or not.

Well it seems that if I slice the extruder @0.3mm layers then there is no bridging between the support block and the main body. Also the bearing hole does not get bridged over. I sliced @0.2mm and now it seems right. I will start a new print with 0.2 layers. This is a lesson for the future.... I need to check the slicing before starting a print!
