Holders for pegboard

Holders for mounting on pegboards also serve as an exercise in expanding my CAD/FDM printing vocabulary, with each iteration refining what works and what doesn't. So far I've designed: * A holder for screwdrivers - shared separately at https://www.thingiverse.com/thing:2405739 * Arms - 4-inch and 6-inch arms (used for hand saws and clamps), along with 6-inch "strong" arms. * A holder for wood rasps. * A holder for metal snips.

Secondary objectives are: * Printable without supports where feasible. * Minimal plastic usage for necessary strength. * Maximum possible strength considering the material used. Note that the parts not visible - the plastic components acting as anchors - were designed to be significantly stronger than standard plastic pegs. The majority of the load is absorbed by the metal screw, while the compressing plastic anchor holds the screw in place against the pegboard hole and its back side. This results in a solid and strong connection. If you need to frequently rearrange items before settling on your final setup, some anchors might wear out over time, requiring replacement prints that take approximately 15-20 minutes. Given the relatively short printing duration, this is an acceptable compromise. Currently, this arm design is suitable for lighter objects but not as robust as desired for heavier items due to FDM print limitations. Specifically, prints are stronger when built with the "grain" of the plastic rather than across it. In the current setup (printed horizontally), the arms are relatively strong, while the base above them is slightly weak. To achieve optimal results, print the arms in the same orientation as they will be used on the pegboard without support structures. However, if printed sideways, you must employ support structures to ensure a stronger base due to the plastic's "grain."
