Tab for magnet organizer

I discovered this nice rotating magnet storage from Boudewijn Plomp  https://makerworld.com/fr/@wbplomp and I really love it. 

You can find the magnet storage here : https://makerworld.com/fr/models/879360-magnet-organizer-with-magnet-tubes#profileId-833136 

But I wanted to store magnets bigger than 15mm which is the maximum size with the original model. If you use a slot without a tube, you can go up to 20mm so I designed this little tab to help lifting the magnet out of the storage.  Hope you like it!
