HDD Caddy for HP ProLiant MicroServer G7 v2

thingiverse

This is replacement of HDD caddy for HP MiscroServer G7 (improved version). Lessons learns after few years of usage of the first version (https://www.thingiverse.com/thing:2835085): 1. The connection of lock and housing parts (with a self-tapping hole) is the most stressed place in the design. A few times it was cracked. Conclusion: Select the correct layers orientation. 2. It has sense to have a whole body as single print (simple, rigit and has right layers orientation). 3. Ventilation could have been better. 4. Springs does not really needed here. Based on these findings I redesign this caddy a bit. There are two parts: main body and lock. Right orientation see on the images. Also you need two two screws with a cylindrical head like DIN 912. The best results were reached with PET-G plastic and tree-like supports (see experemental section in Cura or build them manually). Please note that this is not a clone of the original part. Appearance and shape a little different. Also, the strength and heat resistance of PLA/ABS plastic may be not so hight as of the original part. Update: Screw head dimaeter should be 5 mm, head height between 2.5and 3 mm. I used with thread length 5 mm, howewe it may be longer (up to 10 mm). Please see photo for more details.
