Good job, friend. Do you intend to do the support, to use Bltouch?

OK. Thanks for your contact. Very good your project.

Thank you very much. It's nice to have your work approved, when so many hours of work has been put into the project.

I don't use BL Touch myself, but i'd like to try and add it. I will see what i can do.

Would you know if this would work on the ender 5,

I'm not absolutely sure, but i think the wheels mount plate and the hotend parts is made from the same parts.
You can try print the mount holding the entire system first. It's a few hours print. If it fits, then i think you are all good. Let me know if it worked, if you try. I will see what i can do, if it needs some change.

Well, it doesn't fit at my stock Ender 3 at all...

I need you to be more specific. When you say "at all", does that mean screw holes and everything? I have printed several. Everything fits very well, and I use nothing else than this cooling. Have you calibrated your printer? Overextrusion and too high temperatures, can cause walls to be too thick at some points.
I need information, to be able to correct possible problems.

Sorry for my brief comment. Yes, my printer is calibrated, the print looks great, but I can't fit it on the mounting plate. I can't attach it, because your mount hits the original mounting plate in place where it bends to the back (right side with a groove). It prevents it to position it lower thus the screw hole won't fit. I can press it to fit, but then I can't screw the hotend to place.

Sorry for my bad english, hope you understand.

Okay. Thank you for the update. So if i understand you correctly, the original plate is too thick? The mount has to be placed beneath the sink and clicked into place around the backplate.
It is made to fit tight, so vibrations wont make the mount too noisy. The mount can be attached without removing the "hotend".
Is it possible for you to add a picture?

Somehow I eventually make it fit. The "clicked" part of your reply was the key :) In the attached photo I drew the shape of original mounting plate (yellow line). Your mount has straight groove but the mounting plate is bend to make a belt holding part. Hope it helps.

For now it holds great and I am happily printing again. Thanks.

Aha! Now i see. That extra part is not in the way on my printers though. Might be a little difference between them. I might aswell just cut out the bottom part of it. Thanks for the tip!
I'm glad you got it sorted. Hope it works out for you.

I'm in a hurry to update !!!
