wiper and bucket for makerbot replicator - fits in cutout on back panel of replicator that was intended for this purpose. can be used with skeinforge wipe function to remove oozing filament between layers (especially on dual prints)Print the arm, the bucket and the flames. I suggest using the orientation I have set in the STL files. Cut out a pieze of silicone rubber or other material to use as the actual wiper.Sandwich silicone rubber wiper between bucket and wiper arm, then assemble using #4-40 x 5/8"L machine screws and #4-40 nuts. Flames fit into groove on either side of bucket, held in place by any glue (I used CA glue).Find perforated rectangular cutout on left side of replicator back panel and pop it out, install the wiper the same way the filament spools are mounted. Tweak the height of your silicone wiper sheet if necessary so that it just flicks the nozzles when they pass over it.Skeinforge wipe settings for my machine were as follows (X,Y,Z): Arrival (-130,40,0) Departure (-130,40,0) Wipe (-130,80,0)
