Anet A8 9mm 6 Turn Spring Washers

This is a specialized item, and it's for non-stock bed springs. I used the customizer to recreate the washers I needed. I created this so as to have a link to the spring directly with the washer in case anyone else needs this, too.

I put insulation under my bed on top of a thin piece of wood using spacers and pipe insulation tape. I needed different springs with fewer turns so as to have greater compression. Ball point pen springs could be used, but they didn't have enough pushing power to keep the wood and insulation against the bed. I purchased the springs I wanted off of Ebay, and then I used these modified spring washers to keep them centered around the screw.
