Optical Drive Space SDD Upgrade loose

Hello Guys,

I decided to upgrade\fix computers to help with my Tech Learning journey.

I ripped open the HDD Capacity enclosure for the optical drive because my MacBook Pro wouldn’t close. Does anyone have any experience with putting any spaces or using something to brace the SDD to prevent it from moving in my Labtop.

I’m kind of tight for cash right now but any idea on what products, that you know fit in the 2011 models would be appreciated.

Thanks for your time.
