This is a simple adjustable corner bracket for a glass plate. It fits the Anet A8. Version 3 is in most cases the best choice for you. You can choose if you want to have a hole for an m3 nut. This will make it more durable.

Installation:
You can slide the brackets in and out. To hold them in place i use a thumbscrew (these that normally goes under the h-frame). Under the H:Frame i use 3d printed thumbscrews with m3 nuts. But you have to cut your springs in half otherwise they will be too tight because of the thumbscrew and the bracket itself.

Update: 01.03.17
I uploaded a new version. This bracket is now stronger and easiert to install. You can just slide it in and out but you will need 4 m3 nuts to secure the brackets from underneath. Also it is now universal and should fit more than just the anet a8.

Update 03.03.17
I just made it even stronger and even more universal because mine came loose after a while and they bend the screws.

Update 04.03.17
I saw the remix from rjhuber. Adding m3 nuts was a great idea. But i also like the new version of the bracket more so i implementet this feature in the new version too but i will leave the old version uploaded too. Choose which one you like more. I removed version 1 because i think it was a failure. I just didn't do enough testing. Version two is already usable but i would download the newest model.
