The Damping System
The Damping System
The Dampner
The damper itself is a simple spring powered sliding contact surface device. There's a few parts to it. I truly believe this piece of assembly is the greatest use of common 3D printing materials available in 2025. I used PLA for the Base because of its stiffness, PETG for the top plate due to its thermal properties relative to PLA, TPU for both the inner springs and the top surface for springiness and cushioness.
Using the materials to their appropriate use was the main focus of this assembly. The springs were just any other spring I could get from anywhere. The bolts are just ISO M3 and M2 from the market.
The springs are constrained between m3 washers so they don't make noise once they start moving around.
The star of the show, 51108 bearing. YES SIR, A thrust bearing used as a near frictionless sliding contact.
I had to model the springs for this post, which took a while since I had to make it as close to real life like as possible.
In the 3D models provided below I gave the full system assembly, the assembly without the top plate and the exploded view of the assembly to develop understanding.

Do you know how I got this whole idea?? THE GLASS slabs! YESSSSSSS. The glass slabs when my dad bought and brought them to the house started slipping when kept on top of each other. So I rushed to my old stash of bearings and found a few thrust bearings. I remembered playing around with them back in January and found they slip a lot when turned around and sandwiched with the wrong faces touching the balls.
So I maximized the effect, put the slidy thing in between the slidy things and voila, we have landed on Mars with this situation.

Here's the 3D models of the entire system along with the printer on it and without the printer.
Update: The one with the printer is on hold due to inaccurate models of the A1 Mini printer available online.
