Insert the wiring from the LED Matrix through the opening in the dhp-led.stl part. Fit the LED Matrix into the dhp-led.stl part with the triangle part lined up with the top of the LED (The noticable dots indicate the LED's orientation).
Place the sensor over the barrel and line up the orientation. Carefully insert the distance sensor into the dhp-barrel.stl part with the plastic part going in first.
Insert the Trinket into the dhp-box-bottom.stl part with the USB port facing the port opening. Line up the two mounting holes on the trinket with the holes on the part.
Add two #4-40 flat phillips screws to the dhp-box-bottom.stl part and fasten it together while holding the Trinket down to the part.
Insert the male JST connector from the slide switch adapter to the female JST conncetor on the Trinket.
Fasten two #4-40 flat philips screws into the holes with stand-offs. These need to be inserted so that the heads of the screws are on the opposite end of the stand off.
Insert the male JST connector to the female JST connector on the slide switch adapter.
Insert the 3 x AAA battery holder in the dhp-bottom-box.stl and gently position the cables in between the sides.
Insert the dhp-barrel.stl part onto the dph-bottom-box.stl part with the bottom edge fitting into the opening on the enclosure.
Place the wiring from the LED Matrix through the opening near the top of the battery like in the photo. This wire needs to route through the opening near the triggne and out the handle.
Place the trigger on the enclosure with the heads of the scews resting inside the indents of walls.
Place the dhp-top-box.stl part over the dhp-bottom-box.stl part and make sure wires are not covering the standoffs.
Add #4-40 flat phillips screw to the three mounting holes. Hold down the top and bottom parts together so both pieces are flush when they're secured together.
Position the dhp-bottom-handle.stl part to the battery+trinket enclosure like shown in the photo.
Press down the excess wiring and bend it behind the standoff in the handle.
Place the dhp-top-handle.stl part over the dhp-bottom-handle.stl part and line up the mounting holes and standoffs.
Ensure the two screws in trigger are properly positioned inside the enclosure.
Join the top and bottom handle parts together with machine screws. Fasten three #4-40 flat philips screws while tightly holding the two parts together.
Line up the mount holes on the bottom of the handle and add two #4-40 flat phillips screws to the bottom. Fasten these screws tightly to join the bottom of the handle to the enclosure.
Line up the holes on the top of the handle and add two #4-40 flat phillips screws to the top. Fasten these screws tightly to join the top of the handle to the enclosure.
Postion the dhp-led.stl part over the top of the handle and line up the mounting holes. Make sure the triangle piece is pointing towards the barrel. This serves as line of sight. Add two #4-40 flat phillips screws to join the part to the handle.
Flip the part over and fasten 4 #2-56 flat phillips screws to secure the LED Matrix to the enclosure.
