SNCF (French train company) - Wrench Sockets

Simple but sometimes effective, the SNCF company enquired about making wrench sockets for their emloyees

Why not just buying new ones right ?
Well according to their manager this type of socket is discontinued, and they were the perfect sizes for the toolbox the employees are using, but because they were vacuum forming socket, those were getting broke very often

So i went simple and according their needs : they sent me a vacuum form socket, which was a bit damaged, i made a silicone mold and made solid castings.

Spoilet alert : the employees loved it, while being heavier than vacuum forming plastic, the fact those will never damaged as quickly as before is a huge benefit to their work
