Assembly Instructions

Some parts will need cleaned with a Scotch Brite pad to remove the white residue left on the print surface. These are parts that the print surface is visible in their final assemblies so cosmetics are important. Gently rub a Scotch Brite pad WITH THE GRAIN of the print lines to remove this white residue (see images). Do not rub cross grain because this will cause very visible scratches in the printed part. Once you have cleaned the parts with a Scotch Brite pad, we will need to spray them with compressed air to remove dust, debris, and pad fibers from the printed part. There is a dust vacuum and an airbrush set up in the parts cleaning station. Hold the part in the "cone" of the vacuum while spraying the part with air from the airbrush so that all the debris/dust ends up in the vacuum (see images). Do your best to clean all debris/lint/fibers off of the printed parts.

Some parts need drilled or punched out on the drill press. These parts are:

PP-GP0062 Herringbone Small Gear v1.1 (A)

PP-GP0192 Herringbone Small Gear v1.1 (T6) (M) (A)

PP-GP0224 Bed Mount Table v3.1 (T6)

PP-GP0252 Extruder Fan Mount v2.0 (M)

The Small Herringbone Gears (PP-GP0062, PP-GP0192) need drilled out to ensure a tight fit on the motor shafts. There is a drill out jig that holds a small herringbone gear on the drill press to be drilled out. Using a ___ drill bit place the herringbone gear into the jig and use the drill press to drill out the center of the gear (see images).

The Bed Mount Tables (PP-GP0224) will need the holes punched out. Using the specially made punch and table mount jig for the drill press we punch these holes out. The jig holds the table mount parallel to the drill press table. Without turning on the drill press, place a bed mount table in the jig and align the punch to the center of one punch out holes. Now pull on the drill press handle to drive the punch through the printed part. Repeat on the other punch out hole.

The Extruder Fan Mount (PP-GP0252) will need the two mounting holes countersunk. To do this attach the countersink bit to the drill press. Turn on the drill press and while holding the fan mount line up the mounting holes to the bit, carefully push up to add a countersink to the mounting holes (see images). ONLY DO THIS TO THE TOP TWO HOLES.

Almost all parts printed in Ninjaflex will have little stringers stuck to the outside surface of the print. This is due to retractions and toolhead moves in the printing process combined with the oozing effect of the TPU filaments. In order to clean these stringers off, get some flush cutters and cut the strings/blobs off of the part. Ensure to get as close to the part as possible without damaging the print. Parts that will need these stringers cut off are:

PP-GP0221 Bed Corner Taz6 v2.0 (T6)

PP-GP0237 Flexy Washer v0.1 (T6)

PP-GP0238 Flexy bed Foot v0.1 (T6)

PP-GP0248 Bed Corner Mini v2.7 (M)
