Sidepieces are used to connect to the Wall Control through the 1in slots and extend forward out from the wall. Sidepieces can work on their own with a retainer which can be useful to create a single hook. Alternately, sidepieces can be hooked together via centerpieces to create a wide range of modular hanging solutions.
Sidepiece names start with the dimensions, roughly equivalent to inches as used on the Wall Control system. For example, a 2x4 Sidepiece is 2in in height and extends 4in out from the base (which itself is 8.8mm in front of the wall panel).
Retainers are used when a sidepiece is used without one or more centerpieces, providing a secure fit against the Wall Control board. Standard retainer models are narrow enough to allow side-by-side placement with an adjacent sidepiece + retainer. Locking retainers are wider but can be used with the 8mm lock pin to lock the hanger to the panel. Models are provided in 2/3/4/5/6 inch heights.
Simple, flat-surface sidepieces allowing centerpieces to be mounted vertically against the Wall Control board. Useful with flush-mounted Centerpieces.
"L" shaped brackets, good for lightweight loads or for use as hooks. Models are available with a flat top, or with a 1/4" round "hook" feature which can help to retain parts hung on these models.
Angle brackets good for holding moderate loads, general-purpose solution for mounting centerpieces horizontally. Available in "flat" or "hook" variations.
Square brackets good for holding heavy loads. With a full complement of centerpieces mounted between two square brackets, one can create a "torsion box" which can be helpful for mounting things which might be hanging off to one side of the hanger, presenting a twisting force on the bracket. Available in "flat" or "hook" variations.
U brackets are useful as "hooks" for mounting nearly anything. Use with a retainer to create a single hook which is useful for hanging power tools, or combine a left/right pair of U brackets to hang a drill.
Hangers to hold dowel rods, allowing one to mount things with a transverse hole such as spools.
The sidepieces bear most of the load for an assembled hanger solution. The downward forces press up against a catch on the bottom of the slot hook on each sidepiece, while the outward and rotational forces pull against the top-most portion of that same catch. I've found printing with 100% perimeters in the catch area provides the strongest print. PLA is a good choice for maximum rigidity.
