Magnet sizes and sources

Hello all.  I'm a bit late to the party.  But I decided to finally upgrade my 2S to a 2.5S.  I used the free shipping this last weekend to order all the parts individually from Prusa that matched this sheet.  https://help.prusa3d.com/en/article/upgrading-mk2-s-and-mk2-5-s-to-mk2-5s_20000

Looking at the other parts I need, i think by reusing many from the 2s, and some screws I have on hand, there won't be too much extra things I need.  But I believe the stainless steel ball, and the magnets are going to be a couple (off the top of my head I don't know of anything else).  I can source the 7mm SS ball on amazon.  But I'm having a tougher time with the exact size magnets.  Do you folks think that 5mm wide ones would work with a shim in the slot?  And does anyone see a problem with cutting down a 20mm long one to make a 10mm one?  I also assume these are just normal magnets, and not rare earth/neodymium ones, correct? Or alternatively if someone knows a good source for the correct size magnets (20x6x2 & 10x6x2) at a reasonable price and shipping time, I'd be interested in that as well. 

Thanks in advance folks,

Steven

Chinese filament sensor kits are cheap enough on ebay or aliexpress...

Thanks Joan. 

I didn't know the kits came with both the magnets and ss ball before.  I think you are right, I will just order one of those.  I even see one of the Polish ones on the US Amazon store.  I sorta wish I had noticed that before ordering all the other parts from Prusa, but now I will have an extra sensor (think it is 12v). 

Well at least this post is here for the next person who tries to do the same thing.

Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms.
