Sunlu Filadryer S2 Frame Side Mount for Longer LK5 Pro, CR-10, Ender 3, 2040 Extrusion Mount

I have been looking for a way to mount my Sunlu Filadryer S2 to the bottom side frame of my LK5 Pro since I got it. The stabilizer stand that I remixed this from is elegant and secure, so I decided I would design some brackets to mount this on the lower longitudinal 2040 extrusions of my printer.

The entire is design is intended to be printed without supports.

I ended up with two versions of this mount. The original keeps the dryer feet just above level with the top of the 2040 extrusion. After mounting that, I decided I could lower the center of gravity (and make it look a little cooler) by designing a drop-mount bracket that will have the whole thing sitting about 40mm lower. Both bracket designs have holes intended for M5 heat set inserts for mounting of the cradle to the bracket with M5x8 bolts. For mounting the bracket to the frame, use M5x20 bolts with t-nuts in the rail.

Both bracket designs offset the dryer enough to clear the x-gantry rollers.

For the original, straight bracket design, you will need the S2_Cradle_Bracket and S2_2040ext_Mount_Bracket; print two of each.

For the drop-mount, you will need both the S2_2040_drop_mount_cradle and S2_2040_drop_mount_cradle_L, as well as the s2_2040_drop_mount_bracket. Print two of the brackets.

Print everything with the flat faces down and you will not need support. Pay close attention to how you orient the drop mount bracket on your build plate, as one of the long sides is slightly angled; it will need to lay on the flat side (if you're printing both at once, they will need be mirror-oriented, not facing the same direction). I have uploaded the project file for how I printed them to assist you in your layout.
