Prusa XL felt nozzle wiper

Love my Prusa XL, but hate nozzle leakage, especially with 0.25mm nozzles. There are a number of solutions posted here for using brass brushes, which are great. Unfortunately, my 0.25mm nozzle of choice is E3D's NozzleX, and they specifically caution against using brushes with these nozzles. I've been using a wand with Nomex felt with NozzleX on my MK3S/MK4/MK4S for years, so -→ Nomex felt wiper for the XL.

These were actually printed on my MK4 (before it became a MK4S) with a 0.6mm nozzle, but they should print just fine on an XL as well. Either 0.4mm or 0.6mm nozzle will work. Speed mode is fine, and layer height and infill are not important. The bucket is entirely optional (and possibly unnecessary; I have yet to find any appreciable residue in them).

Hardware needed for each wiper:
(x1) 10mm M3 socket head screw
(x1) M3nE T nut for 3030 extrusion (purchased or printed; there are several designs on Printables)
(x1) 12.7mm x 50.8mm x 3mm (0.5" x 2" x 0.125") strip of high temperature felt (aramid, Nomex; https://www.mcmaster.com/8796K52-8796K72/ - cut a 2" / 50.8mm long strip, then split that strip lengthwise)

To mount: Insert M3nE nut into extrusion under the Nextruder. Center the nut on the lower left coupler pin, then attach the mounting plate with the end stop on the left.

To load: With the open end of the insert positioned with the dovetail on the left, slide one end of the felt into the right (bent) slot (push in from the open side (top); don't try to thread it through), then slide the other end into the straight slot. Slide both ends up against the closed side (bottom) of the insert, then pull on the loop portion to get both ends just below the bottom of the insert. Slide the insert into the mounting plate. Reposition the felt as needed to get it (more or less) centered below the coupler pin. Attach the bucket over the holder if you want to use it. (See photos for reference in hopes of reducing confusion.)

Been using this for about a month with 0.25mm NozzleX and Nextruder nozzle adapters and/or 0.4mm/0.6mm Obxidian nozzles on my XL, and it has pretty much eliminated the blobbing from nozzle leakage. (The leakage on top of the heater block is another story, but that's not the fault of the nozzle wipers).
