This is just a bracket to mount a Lulzbot mini style nozzle wiper (which you can download from here: http://download.lulzbot.com/Mini/1.01/production_parts/printed_parts/wiper_mount_Mini/
You will need two m3 heat set inserts, a pair of M3 bolts to mount it (8mm long), and another pair of M3 bolts to mount the assembly to the bed (also 8mm). Use the assembly as a guide for drilling then tapping 2 M3 bolt holes, or if you have room, a smooth hole and a nut on the bottom. There is support material on the bottom of the notch that needs to be removed, but it's built in so you don't have to generate it.
Wiper 2 is a taller version of Wiper 1, for taller beds. Either one should work.
