Extruder
bottom_bearing_arm One half of the arm on the right of the picture. The two halfs hold a bearing which presses down on the filament as it is forced through the extruder.
top_bearing_arm Other half of the arm exerting force on the filament in the extruder.
bowden_cap This cap screws into the bottom of the extruder and holds the PTFE tube that feeds the filament into the extruder.
bowden_ring This is entirely hidden by the cap, it is a crude collet to grab the PTFE tube and be squeezed by tightening the cap.
bowden_threaded_adapter This is also mostly hidden by the cap. This is what the cap screws onto, and it slides into a matching hole in the extruder.
extruder_body_one Half of the main body of the extruder seen here completely assembled.
extruder_body_two Other half of the extruder.
newnut Large manually turnable nut with internal nut and washer traps to compress spring applying force to filament to hold it against the hobbed gear on the extruder motor.

right-carriage-cap Much like the left carriage cap, but with addition holes to aid mounting the cable chain.
y-carriage-clip Goes on the end of the Y carriage cable chain mount to hold the top of the chain which runs the cables down into the box.
y-chain-mount Attached to the outside of the right Y carriage (though the additional mounting holes on the right carriage) to provide locations to mount connections to the two cable chain segments.
yx-chain-mount Mount point for the cable chain from the X carriage to the right Y carriage. The "roof" makes sure the chain can't hit the top rail.
left_switch_holder Holds microswitch on left Y carriage to detect X carriage moving to home position.
right_switch_holder Holds switch on right Y carriage to detect X carriage hitting max movement limit.
left_stacked_pulley_bracket Belts go through the back corners through independently rotating stacked up pulleys.
right_stacked_pulley_bracket Belt pulleys for the right corner, mirror of the left.
xy-motor-mount Holds a stepper motor upside to drive a belt. (Two motors, two mounts, two belts).
bottom-x-carriage Can't really see much of it, but this piece make the bottom half of the X carriage (and lots of stuff bolts to it in the holes provided up front).
top-x-carriage The top half of the X carriage is where the belts start and end, held in place with toothed wedges and tensioned with adjusting screws in the cylinder shapes.
x-chain-mount The cable chain ties to the X carriage via this piece.
newbeams Support beams for fan mount. They hook around back of X carriage and screw to the front. Holes fit over the nuts holding the wheels on the carriage.
fantop Holds the radial fan with screws, is glued to the rest of the cooling fan structure.
fan-opening Box that connects to fan opening and has vane to divert air to either side. This is glued to the beams and the fantop is glued to the slots.
twoduct This piece consists of two ducts glued to the fan-opening to get the air near the hot end.
newnoz Finally these nozzles fit over the end of each duct and direct the air just below the hot end. They are glued in place.
orion-mount Holds the mount for the Precision Piezo Orion at the front of the X carriage (which, in turn, holds the E3D V6 hot end).
LED lights
left-support Small cone to mate with the rotor holding the aluminum angle with the LED light strip.
lightbox Box to hold wires and switch with a cone to mate with the rotor holding the aluminum angle with the LED light strip.
rotors These hold the aluminum angle with the LED light strip and mate with the cones on either end to allow the light angle to be adjusted by rotating the parts around the cone.
Camera mount
new-camera-mount Hang off top t-slot and hold the camera on a platform with 1/4-20 bolt.
Box parts
conduit-base Piece that sticks up through the box and grabs the end of the flexible conduit by matching the conduit shape.
conduit-top-left Piece that bolts to the rail and grabs the top end of the flexible conduit.
conduit-top-right Mirror of the top left part.
back-cover Holds down end of back cover and provides registration with the little triangular bit.
front-cover Similar to the back cover piece, this holds down and registers the position of the front cover.
handle The covers both have a handle just in back of the magnets that hold the covers down.
z-wire-cover Cover for the Z motor and printbed wires where they enter the box.
chain-end-cover Covers the hole where cables descend into the box from the cable chain.
washer-5mm Custom washers for the M5 bolts that tie down the bottom rails. Truncated on one side because some of the holes are close to the outside wall of the box.
jiggit-ac-power Custom plate to hold AC power connector (salvaged from old computer power supply).
jiggit-data-plate Custom plate for running ethernet and USB connections into the box.
jiggit-fanclip Custom plate that holds a fan inside the box for cooling.
jiggit-rocker-switch Custom plate the power switch clips into.
jiggit-stop-switch Custom plate with hole where the emergency stop switch is mounted.
jiggit-nut-plate All the external plates on the box have one of these matching parts on the inside of the box to hold the nuts used to secure both halfs together.
ssr-cover Found a CAD file for the SSR cover and after much fiddling, turned it into a printable stl.
smoothie-bottom Rail bolted to box, which in turn has one end of smoothieboard bolted to it. Mostly invisible in this picture, but you can see the ends poking out where the bolts come through the box.
smoothie-top Another rail for the other end of the smoothieboard. They aren't the same because the hole layout is different at each end of the board.
smoothie-washer Tiny custom washer needed because things were too tight for the M2 mounting bolt head to fit, so this moves it up where there is space.
psu-riser You can't see them, but the M4 bolts holding the power supply to the box go through these risers.
busbar Washers for the automotive style busbars so I can mount them to the box with M4 bolts.
fan-power Mount for circuit board holding lots of fan headers to provide 12V power for fans that are always on.
cable-tie-16 A collection of cable ties for screwing into the inside of the plywood box to help routing cables.
