Shimano SPD-SL compatible wall mount, with four holes, diameter 4.9mm (M5, M4 countersunk bolts or a countersunk screw fits nicely). Holds shoes neatly, won't come off by accident. Designed to keep the shoe near the wall without touching it. 43 sized shoe has few centimeters between the shoes, .f3d included if there isn't enough room, also version for single shoe here: https://makerworld.com/en/models/211575
Version for Kupper pegboard interface is included.
Print profiles are ready to print. Arachne, four walls is plenty. Tree support for bridges, but really would work also without.
