Wanted covers so the fancy bits on the y-carriage facing the spindle don't get dirty, so I modelled some up.
You are going to need 6 ea 6.1mm ball magnets for each cover, so a total of 12.
Just printed it hard and fast, nothing special.
Step 1: Insert Magnets
Push the magnets into the holes on the piece. I used a c-clamp to press them in flush with the rim.
Step 2: Install Cover
Just put the cover on. You won't have to take anything apart from a stock x-carve (1000mm).
