A quick design of a nozzle wiper/brush mount I through together. It works well enough but I am I think it could be improved. I was really just taking a guess as to what would work. 

There is limited space where the nozzle can reach around the bed that has enough room for a nozzle wiper. I chose the front left so it wouldn't interfere with the camera. The nozzle can only reach the front row of teeth due its limited range of movement.

For the Bambu Lab "Nozzle Wiper" (PTFE roller) cut the small prongs cut off then attached using the provided screw. 

The Bambu Lab “Heatbed Nozzle Wiper - A1” (silicon wiper) attached with the adhesive backing. To install simply clip it around the internal frame on the from left and then push it against the bed as seen in the photos. 

Improvements that could be made: Thinner wiper platform: My current macros lower before wiping, if this does not happen the platform it lifted slightly and which cause the nozzle to hit the roller arm. 

Here is my BoxTurtle/AFC macros variables  file for the brush macro and others for filament changes, look at the brush section. I set the center of the brush off center so the wipe movement hit the roller and the brush.

This should be the position of the toolhead where the cutter arm just
lightly touches the depressor pin
variable_pin_loc_xy               : 1.8, 20    # x,y coordinates of depressor pin
Accel during cut. This will overwrite the global accel for this macro. Set to 0 to use global accel
variable_cut_accel                : 0
Direction to make the cut move (left, right, front, back)
variable_cut_direction            : "left"
This distance is used to move toolhead to cut filament
and to create a small safety distance that aids in generating momentum
variable_pin_park_dist            : 10.0       # Distance in mm
Position of the toolhead when the cutter is fully compressed.
Distance the toolhead needs to travel to compress the cutter arm.
To calculate this distance start at the pin_loc_xy position and move
your toolhead till the cutter arm is completely compressed. Take 0.5mm off this distance
as a buffer.
Ex pin_loc_x : 9, 310  fully compressed at 0, 310 set cut_move_dist to 8.5
variable_cut_move_dist            : 6.0       # Distance in mm
Speed related settings for tip cutting
Note that if the cut speed is too fast, the steppers can lose steps.
Therefore, for a cut:
- We first make a fast move to accumulate some momentum and get the cut
blade to the initial contact with the filament
- We then make a slow move for the actual cut to happen
variable_cut_fast_move_speed      : 32        # Speed mm/s
variable_cut_slow_move_speed      : 10        # Speed mm/s
variable_evacuate_speed           : 150       # Speed mm/s
variable_cut_dwell_time           : 50        # Time to dwell at the cut point in ms
variable_cut_fast_move_fraction   : 0.85      # Fraction of the move that uses fast move 0.0 - 1.0
variable_extruder_move_speed      : 25        # Speed mm/s for all extruder movement
If the toolhead returns to initial position after the cut is complete.
variable_restore_position         : False     # True = return to initial position, False = don't return
Distance to retract prior to making the cut, this reduces wasted filament but might cause clog
if set too large and/or if there are gaps in the hotend assembly
*This must be less than the distance from the nozzle to the cutter
variable_retract_length           : 20
This can help prevent clogging of some toolheads by doing a quick tip from to reduce stringing
variable_quick_tip_forming        : False
Number of times to run the cut movement
variable_cut_count                : 3
Retract length and speed after the cut so that the cutter can go back
into its origin position
variable_rip_length               : 1.0       # Distance in mm to retract to aid lever decompression (>= 0)
variable_rip_speed                : 3         # Speed mm/s
Pushback of the remaining tip from the cold end into the hotend
*Must be less then retract_length
variable_pushback_length          : 2        # Distance in mm Default 2
variable_pushback_dwell_time      : 20        # Time to dwell between the pushback Defaut 20
Safety margin for fast vs slow travel. When traveling to the pin location
we make a safer but longer move if we are closer to the pin than this
specified margin. Usually setting these to the size of the toolhead
(plus a small margin) should be good enough
variable_safe_margin_xy           : 30, 30    # Approx toolhead width +5mm, height +5mm)
Some printers may need a boost of power to complete the cut without skipping steps.
One option is to increase the current for the steppers in printer.cfg. Another
option is to use these variables to set a current that is only used during the
cut motion. Different combinations of kinematics and cutter configurations engage
different combinations of steppers for that motion.  Set the needed variables.
The override is skipped if the current is 0.
Enable if layer shifts occur when cutting
variable_cut_current_stepper_x: 0
variable_cut_current_dual_carriage: 0  # This is the value that is used to define the current for the dual carriage stepper (2nd x) for an IDEX printer during the cut.

variable_cut_current_stepper_z: 0
Change these to match the entries in printer.cfg if needed

The slicer values often are a bit too wasteful. Tune it here to get optimal values. 0.6
is a good starting point.
#variable_purge_length_modifier    : 1
Length of filament to add after the purge volume. Purge volumes don't always take
cutters into account and therefor a swap from red to white might be long enough, but
from white to red can be far too short. When should you alter this value:
INCREASE: When the dark to light swaps are good, but light to dark aren't.
DECREASE: When the light to dark swaps are good, but dark to light aren't. Don't
forget to increase the purge_length_modifier
