Kossel Mini- Protrusions from the print

[solidbass]

So I'm currently trying to design some dice for my friend, however, the printer seems to be producing too much filament around some of the details of the die. If the excess is large enough it appears to be a loop. However, I'm not sure what I can do to fix it. Any help is greatly appreciated thank you.

P.S. I'm printing with PLA on a non heated bed with a bowden extruder.
