HPE Apollo 4200 Gen 9 LFF Caddy

I got a cheap HPE Apollo 4200 Gen 9 for relatively cheap, after I got it, I realized that it requires special caddies and does not use the normal Gen 9 Caddies. As there was no model yet published for LFF ( 3.5 ) disks, I bought one original one and started designing myself a new one. Some pieces got very thin, the problem is there that most of the structural important parts on the original one were made from metal and not from plastic. This version is stable enough when printed with PETG or ABS. As axis for the leaver a short piece of filament is used.
