Ender 3 spring stiffener

Last crawled date: 4 years, 3 months ago

update 3/10/2020: I have now printed continually for over 24 hours since installing these, my print bed is as level as when I started and there is significantly less flex in the bed while printing. I can say without any doubt now that these are a great print for your Ender 3.
This will likely work with any 3d printers springs, but as the only printer I have is the Ender 3 that is what I created it for.
The height of the washer was really random and not a lot of thought was put into it, but it ended up adding almost 2mm of tension to the springs. Not sure how well this will work, it seems to have stiffened my bed, but that could also just be because I think it did. I havnt printed anything big enough to test how well these worked yet, but I am pretty sure they are doing exactly what I wanted. I have included the 3d builder file as well as the stl so if you want to add or remove some tension it should be really easy to edit.
Print these with a brim and 100% infill. The flat washer will go under the side with power running to the bed and the 3 cup washers will go on the rest of the springs like in the photo.
If you would like to support my work, I would never turn down a spool of pla :)https://www.amazon.com/hz/wishlist/ls/2A1T1YEQMIIIP?ref_=wl_share
