I recently upgraded all of the machines in the print farm to a much better print bed which reduces variation in print quality and makes setting up the machines much simpler. The new upgrade is my own design and I have a few plates left to sell.
If you own a Wanhao i3 v2.1, i3 Plus, Maker Select or any other like for like copy versions of this printer, this is a very worthwhile upgrade.
