Voron 0.2 - Góc căn chỉnh bed (Bed Allignment Corner)

These printed corners snap onto the M3 nut.

ABS will soften at elevated temperatures therefore I doubt the press fit will last a lifetime when printing at bed temperatures of 100+. 

You can use simple superglue (cyanoacrylate) which is temperature resistant to bond the part to the bed. Works like a charm for me. 

Don't use too much glue that it oozes out and leaks onto your printer, small droplet will suffice.
