starnut for adjusting / leveling printerbed

This is a nut you will be able to level / adjust your printerbed a little bit better and
more accurate then with the original one or any of the nuts you get here before! Now you're asking why, I'm going to explain it to you. The most popular printers uses to adjust the bed a nut with a dimension of M3. The thread M3 has a lead length of 0,5mm and that is the secret you have to know! for adjusting you've to realise the point where one of the startips has its position. If you are turning this nut in or out from startip to startip you're moving the bed 0,1mm up or down. If you turn it half this way, you are able to move the bed 0,05mm up and down for sure. I think you can't get anything else here to adjust your bed exactlier. The only thing you have to do before using it, you've to press a M3 nut into the hole. Enjoy it!
