If this is the same styrene I think this is, then acetone will be your best friend.
The right scrubs and dashes here and there you can bend it and weld it to whatever configuration you need it to be.
Although word of caution to use this very conservatively. Additionally this is the same styrene that will bend to acetone.
When in doubt, just take the next small step.
With that next step take a deep breath. It calms the mind.
When the mind is calm you realize the best is still yet to come.
