Planar Shock Absorber

I designed this shock absorber structure which is rigid in the vertical direction, but allows horizontal motion. The idea is, it absorbs the lateral forces generated by your printer's motion, without allowing your printer to rock about, which can mess up your print quality.

The weight is taken by four rigid pillars with spherical ends, and the elasticity is provided by a flexible harness which surrounds the ends of the pillars, and acts as a spring to provide the centering force. The spherical ends to the pillars mean the top and bottom surface stay the same distance apart when the damper moves, preventing any bounce in the vertical direction.

There is also a thin pad which you can print separately in your flexible filament, this will prevent the base slipping and marking your table.

I'm using four of these under my Flash Forge Creator Pro, and I have seen no negative impact on the print quality, and it shakes the bench about less than it did before. The default size is 40mm s
