Tool for ajust printer bed screw for easy access

thingiverse

Please use "Larger.stl ",it is the latest modified file, I made the key dia bigger for more comfortable to use. To adjust the printer bed high, you need to move the bed far from the screw to work with, so I cut out the allen key, insert in this knob for easy turning. I made it a bit tight, all you have to do is punch in, and it's tight enough.(Dear all, after use, found that the"gear" diameter a little small, suggest you make it bigger yourself, at the same time, put round corner on all "gear".
