The original was too wide for my bed, so I have recreated it so it's much tighter and fits my bed well. The original was 42 mm, my version is 23 mm. There are 2 version - 1st is the same as the original one, the second has flatter part which lies on the bed frame.

Print with supports, organic works fine, it's not hard to remove from inside the screw hole. Infill up to you, I've printed it with 100% infill and the print took about an hour and 10 minutes.
