Magnetic holders for Solidoodle2 glass bed

This are holders for a glass bed for the solidoodle 2 that are printed in plastic and use magnets to hold the bed in place. I found that this geometry is more effective in holding the bed in place with respect to magnets glued directly to the glass and attached to iron like in http://www.soliforum.com/topic/814/magnetic-glass-bed-mounting/ .
