I've found that the size, isn't the issue (and you're correct, it's 10x20x5mm). Using the magnet from the suction cup the magnet force (with that magnet) is decently strong in my screen mount. Using a "non-stock" 10x20x5mm neodymium, doesn't have the same force. I've even tried a couple designs with stacking 10x20x2mm (x3) and one design with 10x20x2mm (x6) to make sure I had proper coverage. Even found a couple 10x20x6mm's that, again, fall short in comparison to the magnet that comes with the suction cup.I'm not positive but based on the CAD files they provided it looks like they use a 10x20x5mm magnet.
I couldn't find that size in the US so to get them quicker I went with 3/4x1/2x1/8 inch N52. Those dimensions translate to 19x12.7x3.175mm. I did some tests and using one of those was a little weaker than the Radenso mount and using two of them together was stronger, I'm using two of them in the final version of my mount. https://www.ebay.com/itm/151891775798?var=452970698050

Also keep in mind that the attractive force drops off quickly with distance, the thickness of the plastic in front of the magnet on the suction cup mount is only .6mm which is very thin but keeps the gap very small.
To be clear, I'm not changing the space between the mount and magnet (i.e. it remains a constant, if I need further space I build the design out the other way. Granted, not all magnets are created equally, I think I just need to find non-Amazon supplier
Also, for some reason, I always forget eBay exists...
