Strain relief for 3mm wire

Strain relief for 3mm wire

My partner relies on a machine at work that comes equipped with poorly made cables prone to frequent failures due to inadequate strain relief. In an effort to reinforce them for her, I tested several methods, but they ultimately failed to deliver satisfactory results. To improve the outcome, I decided to try something different and was thrilled with the end result. The machine's built-in support material on the bottom must be removed before printing can begin without it. Without this removal, I found it difficult to achieve good yield. The material is 0.15mm thick and therefore constitutes a single layer with the settings used. It can be easily broken off using tweezers. Most other strain relief designs I've encountered on Thingiverse are fully round and printed with the central axis vertical on the plate. This design, however, is rectangular in shape to provide a build surface, allowing it to be printed with the central axis in XY. This modification eliminates the need for support material inside the coils, significantly reducing post-print manual cleanup. I wouldn't be surprised if it's possible to print this without the brim, but using a stickier build plate instead. I'll give that a try (e.g., with glue stick) and if it works out okay, I'll post a model without the brim.
