Introduction

As stated on the summary, this works very well for the rattling sound coming from the chassis.

I would also like to point out that this was not done randomly. I did a study and tried several drawings until I came to the solution that I show you here.

This representation shows that a load of 10N aprox 1kgf will result on a deformation of about 0.35mm, The imagem shows an amplification of the real displacement (better do understand)

Instructions

It is composed of 2 systems: a tensioning system for drive bays and a damping system for the feet's.

you will find 2 kind of damping system for the feet's.

Flex spring_soft - For NAS up to 4 bay (tested with a 920+ model - Don't know about others…);
Flex spring. STEP - For NAS with more than 4 bays.

If, like me, I had a little double-sided adhesive foam, you can put some at the base of each foot. It won't do much about the noise, but it helps to keep your feet in place and in the installation of them.

Conclusion

Did this help?

For me, absolutely, especially the combination of the two systems. Obviously I can hear the drivers spining and the reading head, that noise the drive would always make even if it was resting inside a cotton ball.

For those of you who often ask about the tools I use to bring ideas to life, this article, The Journey From Idea To Object (Part I), offers some insights into the initial stages. It highlights the use of various tools, including software like Autodesk Fusion for CAD design, Blender for render and Bambu Studio for 3D printing preparation, and other...

The print went well. The feet work fine, but the pieces meant to go between the disk drawers don’t hold in place.

@JorgeRui

Replying to @OtakuPrint :

it should work. The bay dors are like the one on the example ? DS920+ ?

@user_2409693857

It turned out very well Of course there's still some noise but nothing compared to what it makes without these parts

Had zero issues with the print, they popped right off the bed and brims super easy. Printed in Bambu PETG HF black.

On a side note for other users looking to print this, i have an DS418play, and the caddy "springs" slide down not giving enough side pressure to hold in place (they almost do, but quite there). Since other users here have complained with different x18 models (namely the DS918+), my guess is these older Synology models had a bit more play/spacing between the caddys than the newer versions (x20 and above). This is not a flaw in the design, since the maker had one of these new versions he couldnt possibly know that Synology messed with the spacings. Anyway, it wasnt wasted material since i'll be giving these to a colleague which has a 923+, which will most likely fit like a glove. I'll say thank you advance for him 🤣

Excellent print. It could be a great solution, let's see when the hard drives are under stress.

I have scaled the spacers between the HDDs for my DS918+ and this works perfectly! I have shared the print profile so other people can also use it easily. Printed it in Bambu Lab PETG HF Yellow.
