Casting resin with results similar to ABS plastic?

Posted in Custom Workstation

I'm in the process of making a storage stand for import figure accessories. I have the piece prepared and am capable of making a mold around it but until I find the right material for the stand I can't continue with the project. Portions of the stand are very thin and will likely snap easily so the copies must be tough and hard to crack when they are cured. What material can I use in the mold to achieve this? Would clear resin work?
