Need assistance printing MMU3 Finda part, overhangs are bad

Hello all,

I am printing out the parts for my MMU3 upgrade. So far so good, except I can't figure out how to get the finda perfectly printed - most of it looks great, but there are 2 parts where the overhang looks terrible. 

I have a stock Mk4, am using the included prusament petg that came with the MMU3 upgrade kit, am printing on the textured PEI sheet, .2, 20% grid infill.  My first layer is 10mm second first layer (the first layer is great). The part is the R4 finda :

I have circled where I am having issues.

On attempt 1, I printed it on the sheet, no supports or anything. The part is fine except for those two overhangs.

On attempt 2, I printed on the sheet and turned on supports only for enforcers, and then painted supports onto the overhangs. The results were arguably worse.

Any suggestions?

It would help if we could evaluate the .3mf file.  Create a .zip copy and upload it here.

ok, I have attached the 3mf (zipping it only saved 4kb so didn't bother with that).

The forum will silently drop 3mf files - zipping them is the only way to get around that.
