Prusa SL1 - platform barrier

This is just a prototype to get some feedback, as I myself am not a frequent user of the SL1 printer, but when I occasionally do use it, the resin mess is the most annoying thing to deal with.
Version 1 is just a basic slope, v2 and v3 add an additional barrier to prevent the resin from even came to contact with the “handling” part of the platform.

Please share your thoughts and suggestions on how to improve it eventually.
