Anet A8 cable strain relief

*** UPDATE / V2 ***
Revisited the design, V2 is smaller, lighter... faster print (1h30m), less filament (13gr), more elegant, and also keeps the back springs tight and straight. Push the springs down the shaft and mount it under the bed. The flat part has to face up. Use a ziptie to fasten the cable to the strain relief. I must say, the result is also pretty rigid, much more than you would assume. Printed this with 3 walls (1.2mm) and 15% infill (grid).
I also added a design for the front spring caps, for the two front corners, so you can bring the bed down to the same height. You can also put the springs inside to keep leveling the bed with the bedscrews or bedlevel knobs, while keeping them straight. I also designed the bedlevel wingnut knobs, for those interested.
Kudos to JAWehrung who designed thing:1895223, it was what inspired me to make the strainrelief this way. Although i didn't remix his model.

PS: version 2.1 is a bit 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 make sure, go for 2.1. Although i did not have issues myself with V2, someone in the comments said the springs were too tight.

*** ORIGINAL INFO / V1 ***
I needed a strainrelief, and since i didn't want to dismantle the entire bed (bed + carriage from the bearing blocks) to install one of the existing strain relief designs, i designed a new one.

I wanted it to be:

• an easy print (no supports or overhangs etc)
• a relatively fast print (at about 2.5 hours)
• an easy install (no need to dismantle the bed)

I'm very aware this is not the most elegant solution, i didn't work on this for very long, but it works, and you only need to remove the back two screws from the bed in order 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 you see fit (depending on your setup). Print time should average around 2h30m with roughly 30gr of filament needed. No supports needed, just print it flat on the bed. Depending on your bed adhesion, you might want to consider printing a brim, since flat/long designs are prone to curl if your adhesion isn't that good. 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°).

The design is made to screw the bed all the way down, to ensure it stays snug and won't slant or sag. If you don't wish to screw your bed all the way down, there are holes for extra springs, to keep the strain relief lifted and keep it from sagging in the middle. These extra springs are not needed if you screw the bed down as intended, and compress the corner springs all the way.
