Used for attaching an lm8uu linear bearing to a heated bed.
Use a block of insulating wood between the bed and the holder to prevent the holder from softening.
Again, use a cable tie to make sure the bearing is held firmly.
I use 3 of these for to support the bed.
The holder is attached to the block with 2 countersunk wood screws.
The block is attached to the bed with a single countersunk wood screw.
This means that it is self aligning and there is no need for precision drilling.
