I designed this scissor bracket to attach to a vertical surface with an adhesive strip, rather than a screw mounting bracket that came with the scissors. The main difference is a flat surface on the back of the bracket. I printed it in PLA, 0.2mm layer height, quality setting on my MK3S. I recommend printing it upright (avoids overhangs) with an 8mm brim. The groove on the back accommodates a size Large Command Strip.
