Voron 2.4 In-Skirt Revo Nozzle Holder (Remix)

First of all, thanks to Daten for sharing his original mod and providing the stepfile, which made doing this practical.

My original goal for this was just to add a magnetic closure to hold the door closed.  While I was at it, I made several other changes to hopefully improve the utility of the mod.  First, I got rid of the M3 screws as hinge hardware, and replaced them with a simple piece of filament inserted through the top.  This allowed me to move the hinge point closer to the corner of the door, while eliminating the possibility of cracking out the door around the screw threads as other makers of the original have commented.  Second, I changed the nozzle holder itself to hold all of the nozzles pointing up in the same orientation, and I found that it was possible to fit 4 nozzles in the door, instead of the 3 only that the 300mm version originally held.  I also removed the text from the door because it annoyed me.

There are undoubtedly other improvements that could still be made…  I stopped tweaking it once I had the function I wanted.  Magnets used are 5mmx2mm nominal round magnets, although the ones I have are actually 1.7mm thick which is what the parts are sized for.  They should be a press fit with glue being optional.  I printed my parts out of Polymaker ABS using a 0.4mm nozzle, and the standard Voron parts settings which are probably overkill for this application.  The uploaded files will make the parts for a nozzle holder on the right side of the printer; if you want to put them on the left, mirror them in your slicer or just use the .3mf file.

UPDATED 22MAY2023:

I had a request for a version using the 6x3mm magnets that are used all over the Voron printers for various things, which in hindsight I should have expected since most who have built a Voron will have some of them left over (including myself).  I originally used the 5mm magnets because I had some, and they are perfectly adequate.  I have no plan to change out the nozzle holders on my own printer for the 6mm version, although I did print and assemble one to check fit and function prior to uploading the files.

While I was editing the CAD, I took the opportunity to clean up one light interference where the door dragged on the boss holding the magnet as it is swung open.  It barely made contact, and again, I won't be changing out the parts on my printer for the new ones, but the new parts have enough clearance to prevent the contact.  I also updated the 5mm version to fix this.

One other small note, the holes for the filament hinge are a little tight on purpose.  I made test prints with several different hole dimensions, and intentionally chose a size for the door that will result in a small amount of drag, so the hinge won't be sloppy.  Plan on working a scrap length of filament in and out of the holes a few times before you try to put the pieces together.
