Tevo Tornado Bed Spring Mod - Reduced bed wobbling + glass protection

thingiverse

There was too much play in my glass bed, the whole thing would wobble along the Y axis. The only way to negate this was to print at very slow speeds. After looking at the options, I ended up designing a wide foot spring assembly with springs found at my local TV hardware store. The spring cups were designed to work with a 25mm long, 15mm diameter spring with wire width 1.2-1.5mm. You may be able to find these at your local hardware store. The bed washers are designed to protect your glass from contact with the metal screw and reduce slop from the oversized hole in the glass. I had problems with my thumbnuts moving coming out of adjustment on long prints, so I am using M5 locknuts instead. An aluminum quadcopter locknut is shown. My printer stays level now instead of needing constant tweaks. Print the cups with heavy walls and high infill. Print the washers with .4mm walls.
