I recommend to print with regular PLA
Silk PLA is a very difficult material choice for this part.
Some matte PLA colors might work
I print with overture pla, from my experience here is how some of the colors behave:
Green and Blue colors generally are not as forgiving on tolerances. Silvers and bronze also can stick hard.
white, orange, and grey seem fine
Some orange PLA batches I fine to be near perfect on accuracy. 0.005 mm or better on the calipers to my amazement. White shrinks slightly .1mm to .05mm.
Olive green expands like crazy - would skip
regular green seems ok
Silk bronze green I did pull off with this print later.
To break free gently compress it to a slight elliptical shape and roll that eliptical shape around it to break any sticking planets up. Gently or you will break it or permanently distort it.
To make it spin even better use the water trick I found.
The Water Trick:
Put it in water bowl or running under a tap and move it. It must move under the water. Sitting in water will do nothing. Move and work it in under water. After a while pull it out and dry it. When its fully dry it should spin well - dependent of course if your material is good and your printer did a good job.
