Nerf Vortex Proton - Roller replacement

I needed to fix my Nerf Proton so I've made this part. This is a replacement for a part that is primary culprit behind priming failure. Punch out the pin that holds shattered remains of the old wheel, put the replacement roller inside and use pliers to secure the roller inside.

Print in material you feel confident that won't shatter too quickly from continuous blows. 
30-50% gyroid infill should suffice. Supports not necessary.
