Main assembly
Fitting the Motor Gear
Take the motor and the smallest gear — this is the motor gear. It has a flat on its bore that matches the flat on the motor shaft. Line the two flats up and press the gear all the way onto the shaft, down to the stop.
The gear has two holes — install a set screw (M4×5) in each, one from each side. Tighten until snug, but keep in mind this is plastic: as soon as you feel the resistance increase, stop. Don't overtighten.
Mounting the Motor
Insert the motor, with the gear already fitted, into the holder. Line up the hole on the holder with the hole on the motor, then secure it with a countersunk M3×5 screw.
On the other side there's a second hole — install another M3×5 screw and drive it in with a hex key, reaching it through the dedicated access hole in the body. Tighten it all the way.
Preparing the Gears
The gears print with pre-made supports already in place. Remove these supports, then fit a bearing into each gear where the supports were. There are four bearings in total.
Assembling the Main Gear
The main gear comes as two separate parts, since it's difficult to print in one piece. Fit the two halves together; for extra strength you can glue them. Just make sure no glue gets into the bearing — this is very important, as it can damage the bearing later.
The last photo shows how the finished gear assembly should look.
Installing the Large Gear
Place the large gear into the body and center the bearing's hole with the hole in the body. Insert an M4×20 screw, fit an M4 nut on the opposite side, and tighten the screw into the nut. Run it down to the stop, but only so far that the gear still spins freely.
Fitting the Chain Sprocket
Take the sprocket and loop the chain over it with the teeth pointing counterclockwise, as shown in the photo. This sets the chain to run in the correct direction once everything is assembled.
Insert the sprocket together with the chain into the body so that its teeth mesh with the teeth of the large gear. Secure it the same way as the large gear — an M4×20 screw on one side, an M4 nut on the opposite side — and tighten.
At this point you'll have a fully assembled gearbox with the chain in place.
Installing the Gearbox
Take the main body and lay the chain into it down the middle. Then slide the gearbox into the body, as shown in the picture.
Take a spring and line up its eyelet (the loop at the end) with the hole, then fasten it with an M3×5 screw. Line up the spring's second eyelet with the hole on the gearbox and fasten it the same way, with another M3×5 screw. Repeat the whole process on the opposite side. In total you'll need two springs and four M3 screws.
Once both springs are in, check that they work properly — the whole assembly should travel smoothly along the rails without binding anywhere.
Installing the Blade
Line up the holes on the blade with the holes on the main body and fasten them with M3×5 screws — two screws on each side.
Fitting the Chain to the Blade
Now loop the chain over the blade. Because the gearbox sits on the springs, it can move to let you tension the chain. Brace your thumb against the blade, pull the chain with your index and middle fingers, and finally use your ring finger to draw the chain up and over until it seats onto the blade.
Installing Shell 1
Fit the Shell 1 part, fastening the countersunk section first with an M2.6×6 screw. Then take the bracket, set it onto the shell and the blade, and secure it with two M2.6×6 screws. Repeat the same steps on the other side.
Installing Shell 2
Take the Shell 2 part. Slip one end onto the blade first, then seat the part fully, lining up the holes. In the holes closer to the main body, drive in an M2.3×10 screw. Next set the bracket onto the shell and the blade and fasten it with M2.6×6 screws. Repeat the same steps on the other side.
Installing Shell 3
Set the Shell 3 part onto the main body, lining up the holes, and secure the upper hole with an M2.6×6 screw on each side.
Adding the Decorative Chain
Take the decorative chain, fit it onto the main body, and fasten it with a single M2.3×10 screw.
Next take the left bracket and hold it against both the decorative chain and the Shell 3 part. Fasten it to the decorative chain with an M2.3×10 screw, and to the Shell 3 part with an M2.6×6 screw. Repeat the same with the right bracket on the other side.
Installing the Button
Feed the button's wires through the hole in the main body. Angle the pins inward and slightly tilt the button, then push it all the way into place. Secure the button in the body with M2.3×10 screws.
Installing the Trigger
Next fit the trigger. The trigger has a flat cut on it — position it so that flat faces up, toward the hole, as shown in the picture. Then drive in an M3×16 screw, tightening it just enough that the trigger still rotates freely. Don't overtighten it.
Attaching the Handle
Screw the handle into the body.
Installing the Display
Take the display and insert it into the slot in the main body's cover, with the dots facing down — otherwise the digits will appear upside down. Then secure the display with M2.6×6 screws.
