Description
Our original cable guide (https://www.thingiverse.com/thing:4618230) failed because our workspace gets warm enough, and we had enough cables, that the hot glue failed. We needed a new cable guide.
Our new cable guide adds an 11/64" screw hole (chamfered) in the base and puts a hole through the bottom of the hook large enough for a screwdriver. We thickened the base (3/8" from 1/4"), increased the hook fillet for strength, and made it taller (3/4" up from 1/2").
Along the way we made the base a bit shorter (1 3/4" from 2") although the hook is curved so the overall footprint is greater, it's under 2". It's also less "pointy" so it'll hold more cableage. The cable opening "slot" is around 1/4" but is flexible enough to allow shoving larger cables in.
We've been using 1" #6 screws with a coarse thread (like a drywall screw so we don't have to drill a pilot hole in the target) and it appears plenty sturdy, even in particle board, but we thought that last time, too. It seems pretty solid so far. The choice of a single screw mount... we're not sure about that: our current usecase has them flushed against a crosswise support piece so they can't rotate anyway.
We printed these at a 15%, cubic infill and it's pretty sturdy. The main picture shows three power strips (and two random cables) being supported by a single hook, which causes ~2mm of deflection. IRL we have five of these across the back so we don't anticipate any load problems. Over-engineering, anyone?
The current design lacks a chamfer around the edges (we forgot) but we'll update this.
