Case Assembly

	Secure Case to Mount The Tripler FeatherWing case is attached to the left bar mount using machine screws and hex nuts. Use the following hardware to secure these parts together. 2x M3 x 8mm screws 2x M3 nylon hex lock nuts
	Secured Case Mount The M3 nylon insert hex nuts are press fitted into the holes on the inside of the left bar mount. Fasten the screws until they're fully tightened.
	Bottom Cover Screws The bottom cover requires the following hardware to secure the Tripler FeatherWing. 8x M2.5 x 4mm machine screws 4x M2.5 x 6mm female-female standoffs
	Install Standoffs Insert the M2.5 x 4mm screws through the bottom. Press fit them through the outer four holes on the cover. While holding the screw in place, add a standoff and fasten it tightly.
	Secure Battery Holder to Cover Place the battery holder under the cover and line up the mounting holes. Press fit screws through the remaining mounting holes. Use the following hardware to secure the parts together. 4x M2.5 x 6mm screws 4x M2.5 hex nuts
	Secured Battery Holder Here's the battery holder secured to the bottom cover. The mounting holes are symmetrical so it orientation of the parts doesn't matter.
	Secure Tripler FeatherWing Place the Tripler FeatherWing over the standoffs and line up the mounting holes. Insert and fasten the M2.5 screws to secure the PCB to the standoffs.
	Install Case to Botton Cover Position the case over the bottom cover and press down to snap them together. The case is also symmetrical so orientation doesn't matter.
	Installed Case The bottom cover features snaps that lock onto the nubs on the inside of the case. This allows the two parts to snap fit together.
	Install Motor Wires Grab the four wires from the stepper motor and begin to insert them through the hole on the inside of the left bar mount. Use pieces of heat shrink tubing to keep the wires bundled together.
	Motor Wiring Push and thread the wiring through the case and out the hole on the other end of the case. You can optionally remove the Triper FeatherWing to gain easier access to the wiring.
	Stepper Motor Wires Pull out the wires from the stepper motor through the hole on the end of the case. If the wires are too long, you can optionally trim them short.
	Installing T-Nuts Insert and fasten two M4 x 8mm machine screws to the tabs on the side of the left bar mount. Fit the M4 oval t-nuts onto the threads of the screws. Fasten the screws so the oval t-nuts are secured to the threads. Don't fasten them all the way just yet.
	Install Mount With the oval t-nuts installed to the screws, start to fit the left bar mount onto the aluminum extrusions. Adjust the oval t-nuts so they slide into the profiles of the aluminum extrusions.
	Install Battery Carefully begin to flip the whole build upside down. This will make installing the battery pack to the battery holder much easier. Grab the 12V battery pack and start to fit it into the holder. The clips can flex slightly so they grasp onto the battery pack.
	Battery Orientation The battery is oriented such that the built-in slide switch is accessible and wiring is able to reach the Motor FeatherWing.
	Connect Stepper Motor to FeatherWing Grab the Motor FeatherWing and connect the wires from the stepper motor to the screw block terminals. Reference the photo for the correct placement of the wires – Polarity matters here so follow it carefully. Use a screw driver to tighten the screws and secure the wires in place.
	Connect Battery Wires to FeatherWing Insert the voltage and ground wire from the 12V battery pack to the screw block terminals. The power port is located on the side of the motor FeatherWing. Fasten the screws to secure the voltage and ground wires from the battery pack.
	Install Motor FeatherWing to Tripler Press the Motor FeatherWing onto the headers on the Tripler FeatherWing. You can choose to install it on any of the three available sets of headers on Tripler FeatherWing.
	Install Mini TFT FeatherWing to Tripler. Press the mini TFT FeatherWing onto the headers on the Tripler FeatherWing. You can choose to install it on any of the remaining sets of headers.
	Install Feather M4 to Tripler Finally, press fit the Feather M4 on to the remaining set of headers on the Tripler FeatherWing. Again, you can rearrange the FeatherWings however you see fit. Make sure the 400mAh lipo battery and JST cabling is not being kinked or pinched by the headers.
	Installed Case Assembly Thoroughly inspect the wiring and make sure all of the wired connections are properly placed and secured. Remember to turn on both switches, the one built into the 12V battery pack and the slide switch soldered to the Feather M4.
