Dump bucket for BigBox printer with linear rail

With the rebuild of the E3D Bigbox with linear rail (thing 2519833), the dump bucket / nozzle wiper in the back of the printer is not usable anymore. However, there is plenty of room at the front of the printbed, room enough for a nozzle wiper with dump bucket.

Parts used:
1x Shank Polishing Brass Wire Wheel Cup Brush (ebay part# 201707717566).
1x Silicone sheet 1mm (ebay part# 272854781845).
3x M3 hex screw and nut

Both the height of the cup brush and the silicone wiper are adjustable (see pictures)
