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