Anet A8 cable strain relief

*** UPDATE / V2 ***\r\nRevised design, V2 is more compact, lighter... quicker print (1h30m), less filament used (13gr), sleeker appearance, and maintains back springs tight and straight. Lower the springs down the shaft and attach it under the bed. The flat section should face upwards. Secure the cable to the strain relief using a zip tie. I must admit, the outcome is also quite rigid, much stiffer than expected. Printed this with 3 walls (1.2mm) and 15% infill (grid).\r\nI also designed front spring caps for the two front corners, allowing you to bring the bed down to the same height. You can also place the springs inside to keep leveling the bed with the bed screws or bed level knobs while keeping them straight. I also created a design for the bed level wingnut knobs, for those interested.\r\nKudos to JAWehrung who designed thing:1895223, it inspired me to create this strain relief design. Although I didn't remix his model.\r\n\r\nPS: version 2.1 is slightly less tight inside around the spring than V2 (but otherwise identical), so if you're having trouble getting the spring to fit with version 2, or if you just want to be sure, go for 2.1. Although I didn't have issues myself with V2, someone in the comments mentioned the springs were too tight.\r\n\r\n*************************\r\n\r\n*** ORIGINAL INFO / V1 ***\r\nI needed a strain relief and since I didn't want to disassemble the entire bed (bed + carriage from the bearing blocks) to install one of the existing strain relief designs, I created a new one.\r\n\r\nI aimed for:\r\n* an easy print (no supports or overhangs etc)\r\n* a relatively fast print (at about 2.5 hours)\r\n* an easy installation (no need to disassemble the bed)\r\n\r\nI'm fully aware this isn't the most elegant solution, I didn't spend much time on it, but it works and you only need to remove the back two screws from the bed to install it. So installation should be much faster and simpler than with most other A8 strain reliefs. The 8 holes are meant for zip ties, so you can route your cable as needed (depending on your setup). Print time should average around 2h30m with roughly 30gr of filament used. No supports required, just print it flat on the bed. Depending on your bed adhesion, consider printing a brim since flat/long designs are prone to curl if adhesion isn't good enough. Use 0.2 mm layer height and 2 walls with a 10-15% infill. The design easily fits an A8 bed (see picture). Best printed with ABS if you intend to heat your bed higher than PLA temperatures (+/-50°).\r\n\r\nThe design is made to screw the bed all the way down, ensuring it stays snug and won't slant or sag. If you don't want to screw your bed all the way down, there are holes for extra springs, to keep the strain relief lifted and prevent it from sagging in the middle. These extra springs aren't needed if you screw the bed down as intended, and compress the corner springs all the way.
