I got tired of seeing the wires just hanging there on the right being ugly. Especially since the small one kept coming out of the small channel for it and hanging slightly. So I designed this to cover them up and keep them contained. I recommend printing it as shown in the pic with supports. (don't worry, that's the side you don't see)

I printed it in PLA but use whatever works for you. Supports are necessary. When putting it on tuck the bottom edge in first and just kinda roll it on over the top. It should flex enough to get on there but it does take a little force.

One very important note: Be sure to slide it all the way to the back after putting it on. Be sure the front edge is behind where the bottom lip ends on the machine. (see last pic) If you don't, your bed will crash into it and prevent the bed from coming up far enough to print anything other than spaghett. (Don't ask how I know. lol)
