Thank you so much for your effort.

Still a little bit difficult to squeeze all wires into the box, but very nice design and works as expected. Thanks for creating and sharing this model!

Very nice! Why did you decide to design the middle screw upside down (with the nuts upward) instead of following the original Prusa design of having all nuts on the bottom side?

With the Prusa design, when tightening the screw you have to hold the nut underneath the heatbed with a socket or pliers. It's awkward to do. WIth my design, the nut is captured in the upper shell, and so all that's needed is an allen wrench. It's much easier to install.

I see, thanks for the details. I'll try this.

Worked perfectly on my MK3S.

I would like to remix this part, is it possible to add solid files to package also?

I am unable to fit this after I printed it. The red insulators on the connectors are almost flush with the heat bed and don't allow much room to bend the entire cable. Making the neck of the top part longer longer would. I have attached 2 images showing what I am talking about. In the "Bottom view" image, you can see that the slot for the cable is way to the upper right and bending the cable to fit this is not advised, especially because the insulators won't allow the cable to bend.

Any ideas How I can make this work?

Even though the cover has more room than some other covers, it's still a difficult fit. See the picture below for how it fits on my MK3. Yes, one of the wires has quite a sharp bend. Remember though that that's a one-time, non-repetitive bend, and should not be a problem. Also, others who have made this part report that flipping the connectors over allow them to be angled in such a way that there is less bend required to get the cable to fit.

Making the neck of the top part longer longer would (help).

Perhaps, but I found that making the neck longer puts the cable under tension.

Printing this one at the moment ^^
I was testing out the other version from T1miverse but when I saw how it was bending everything.. So went on thingiverse and found this one ^^
If the print is good and mounted then I will add it to the makes list :)

Here are a couple of pics of the LightBlock version in Prusa orange - makes for a nice soft glow.

This part works perfectly, except it still exposes that incredibly annoying flashing light. I've remixed and attached a version that closes the gap. Print in a light color and you have a flashing glow instead of a harsh light. Print in solid black and the light is gone altogether. Can you please post this version with your Thing Files?

Thanks. Works great. Also possible to direct the cable in an angle to accommodate for a smooth scrawl and little conflict with the x-carriage cable.

I works very well, thank you
