Anet Bed Spring Insert

thingiverse

Small spacers should be inserted between the bed springs and adjustment screws. When using an Anet, you'll soon notice that your bed adjustment screws start to bind. This happens because the springs rub against them, gradually wearing down the threads over time. As a result, cross-threading can occur in either your bed carriage or wingnuts. These spacers will prevent this from happening. They're designed to be short enough to allow the spring to fully compress while keeping it from ever touching the screw.
