Xacto #2 cap (x3202)

I bought an Xacto knife (model x3202) to clean support off my 3d prints and it came without a protective cap, so I designed one in Solidworks.

My first design had the hole diameter just right at 11.35mm according to my measurements but my printer (Ultimaker 3) ended up printing it too small at about 11.10mm which seems to be a common problem. So I extended the size of the hole in the model and now the print fits snugly.
