Recently purchased a ts60 and found that the arbor hole was a different dimension to the usual ts55 had a look on the usual susect sites for a file to print but could only find paid versions so knocked up my own on onshape and here it is for you to use.
cover is a snug fit and snaps in place so no need for any extra tabs but feel free to add some.
printed mine in pla using 0.2 layer height.
The author marked this model as their own original creation.
