Pet+ as a good alternative to ABS

yeah from what i can tell you have 2 things going on there. the main thing is with doing something tiny like that your going to get the part very heat soaked. each layer doesnt have enough cooling time. are you using your bed fan? you should use it same as with pla....atleast on small stuff like that. it looks like your pumping out alot of plastic, however this could just be that the model is too hot. nothing to do with the blobs but looks like that 1st layer could be printed just hair closer to the bed. i have found that the opaque colors, atleast the black needs more retraction that the clear stuff. i am running some black right now and here are my settings:

retraction 4.40mm
coasting distance 2.8mm
temp 245. (this is a block style hot end, actual nozzle temp is 225)

be sure to measure the filament and set that right. that could give you lots of blobbing due to over extrusion. i would try a more simple model first to atleast get the stuff extruding correctly then work on the tricky stuff. maybe start with some calibration objects. cubes, cylinders. there is tons of that stuff on thingi.

i do know a thing or two about boats. #1, i hate them, #2 i was a marine mechanic for some years then worked for viking yacht co for quite a few more as both a service tech, engineer and about everything else at that place of course #1 is a result of #2
