Ok, one more last question lol. Should I polish the acrylic in the corners prior to doing the rods? Or will the solvent address imperfections?
No need to polish it. You might want to experiment a bit here also tho with any extra material u may have. Typically just a regular table saw cut will adhere clear/bubble free as the solvent melts the material a bit. Being so thick the seams might come out better running a router with flush trim bit over it after the saw cut.
