Screws & Nuts for Smoby workbench

I bought for my kid the “Smoby - Black+Decker - Etabli Bricolo Center” which uses 20 of the "92 Accessoires" as mandatory use for mounting it. I took it as a challenge to recreate the screws & nuts so that my son could use the ones meant for mounting the stand. Because this was my first 3d design, the model is not perfect, but it does the job.

Funny enough, one of the screw prints failed which halted halfway, but it was all fine, it just made a half-sized screw :D
