Case for AmScope WF20x 20x Eyepiece for SE400, SE305, SE306

I just got my AmScope SE4000-Z microscope and intend to use the 10x eyepieces most of the time. So i needed somewhere to store the 20x (WF20X) eyepieces

So I have made a case and lid to protect them.

I am pretty sure this will also fit the SE305 and SE306 eyepieces and certainly other AmScope models too.
