A bolt protector for a Musgrave. Could do with the centre hole being a bit tighter but it fits fairly nicely.

I printed this on an XYZ Davinci 1.0 with Slic3r to make hex fill, these arn't overly precise so could possibly come down 1-2% and still fit if it were printed on a decent machine.

I printed one with supports and one without, both worked but the supports needed careful poking with a sharp chisel to remove (there is a lug recess at the bottom which forms about a 5mm ridge.
