Snapmaker an cable strain reliefs... As an electrical engineer, it hurts my heart when I take a closer look at Snapmaker's great products from the outside and discover that no consideration has been given to the service life of the electrical cables. Two places that cause the biggest problems and you hear most of the complaints are the display cable and the cable from the heated bed. Because my first design (https://www.thingiverse.com/thing:4695640) has so many downloads, I wanted to go ahead and improve the design further. Since I wanted to install a drag chain (more for visual reasons), I designed a few parts. You only need a few extra parts: 2 x M4 nuts and 4 x M4x12 or M4x14 screws (DIN7984 like the screws from the Snapmaker) I used the drag chain from https://www.thingiverse.com/thing:4783019. For my A250 I used 17 links and maybe I rotate my back plate of the enclosure to change the position of the enclosure fan. But because not everyone wants a drag chain, the design can also be used without it. The adapter on the heating bed has built-in strain relief in the clamping area of ​​the M4 screws and the angled shape ensures that the cable is not pressed against the enclosure. There is also a minimalist holder without a drag chain link just for the display cable (no picture). PS: Normally, cables have to be suitable for drag chains and I'm not sure whether these are the cables of the Snapmaker. Rather, I think it is PVC cables and not PU - therefore actually rather unsuitable.
