Bed clips made for glass heatbed. they work really really well, and they are much more convenient to take off and put on than traditional bed clips. Also you can print them in any color to match your printer. They are the only clips I use now and I have been printing with them for awhile now and have had no issues whatsoever.

For best results print in ABS, especially if you heat your bed really hot. If not PLA will work just fine.

Hope you enjoy!
