Lego wall mount brackets and hooks

Various hooks and brick-style wall mounts for legos. Hooks work well for technics. Bricks work well for lighter traditional models. I was inspired by this mount which held my two technic cars up very well: https://www.thingiverse.com/thing:3638962 The cars a heavy, so a screw and wall anchor adds some peace of mind. But for most legos, simple slant nails are more than adequate and easier to set up. So all the mounts I designed are nail in style, like pictures hangers.
