Bernina 880 Knob Protector

This is a Bernina 880 knob protector for when the machine is being transported. Apparently the knobs like to get knocked off fairly often.

This one fits my Bernina 880 that is from 2012, but I don't think the knob spacing has changed from then to now.

I printed it with 15% infill since I didn't need it to do anything very structural, just protect the knobs.
