Note that additional parts are required for the extruder, although some extruder parts are included in the table below.

Required

Quantity	Description	Type	Comments
83	M8 nut	Fastener	Buy a 100-pack to be on the safe side.
93	M8 washer	Fastener	Buy a 100-pack to be on the safe side. (Grade 2 works fine.)
6	M8×30 mudguard / fender washer	Fastener	These are also known as penny washers, they have a much larger outer diameter than regular washers.
2	M4×20 bolt	Fastener	To mount the extruder
2	M4 nut	Fastener	To mount the extruder
2	M4 washer	Fastener	To mount the extruder
22	M3×10 bolt	Fastener
16	M3×25 bolt	Fastener	Or eight M3×25 bolt plus eight M3x20 bolts. The M3x25 bolts are too long for the recent Prusa z-motor-holder and rod-clamp, and also for the Z motor couplings. See Section 8, steps 4 and 13 for details.
4	M3×40 bolt	Fastener
70	M3 washer	Fastener
40	M3 nut	Fastener	8 optionally locknut / stop nut / nyloc
2	M3 grub screw / set screw	Fastener	M3x8 seems about ideal but anything 6mm or longer should do. If these are hard to get, additional M3×10 bolts will do the job instead.
3	608 roller skate / inline skate / skateboard bearing	Bearings	You don't need to ask for a "608 bearing" at a skate shop, just ask for wheel bearings.
4	ballpoint pen springs	Spring	To fit over M3 bolts. Ballpoint pens are a common, cheap source of suitable springs. They are about 25mm long and compress to about 10mm.
6	M8×370mm	Threaded rod	3 per side Note: The threaded rods can be cut from larger 6x1m pieces (see Threaded Rod Cut Order below).
4	M8×294mm	Threaded rod	front / rear
3	M8×440mm	Threaded rod	top / bottom
2	M8×210mm	Threaded rod	Z-leadscrew
1	M8×50mm	Threaded rod	or M8x30 or longer bolt for X idler. Take care: if the bolt is too long, it may not be threaded along a sufficient length
2	8mm×420mm	Smooth rod	X-bar Note: 304 Stainless Steel, A2 Tool Steel, or O1 Tool Steel are recommended for smooth rods as it can help to prevent friction from rust and manufacturing (straightness) standards are higher. Rust issues can be prevented on the normal steel rods by maintaining a coat of oil. The smooth rods can also be cut from larger 3x1m pieces (see Smooth Rod Cut Order below).
2	8mm×406mm	Smooth rod	Y-bar
2	8mm×350mm	Smooth rod	Z-bar
1	225mm×225mm print top plate	Thick Sheet
1	140mm×225mm print bottom plate	Thick Sheet	Note: The Prusa Iteration 2 design does not use a print bottom plate.
1	840mm×5mm T5 pitch timing belt	Belt	Y axis
1	900mm×5mm T5 pitch timing belt	Belt	X axis
5	NEMA 17 bipolar stepper motor	Stepper	Be sure to get ones with at least 20mm of shaft length. Shorter shafts require modifications to the X pulley assembly and Z motor couplers. One of the five motors, for use with the extruder, should be capable of creating a holding torque of at least 40Ncm, at the very least.
50	small cable binder / ziptie	Misc
1	Wade's Geared Extruder		for 1.75mm filament RepRap Universal Mini Extruder; or any other compatible extruder for either
1	Electronics + endstops		This can be RAMPS, Sanguinololu, Gen6, Gen7, Gen3, or any other Mendel compatible electronics. Endstops are either optical switches or microswitches (Recommended), and you need three, one for each of the X, Y, Z axes.

Optional

Quantity	Description	Type	Comments
3	30mm×10mm Optoflags	Thin Sheet	if using opto endstops
2	8mm ID spring	Spring	to eliminate backlash in the z axis
1	object with precisely 290mm length		for frame alignment
1	object with precisely 234mm length		for frame alignment

Note: You can combine the latter two by having a piece of thick sheet with dimensions 290mm×234mm. Make sure to mark which side is which.

Threaded Rod Cut Order (when cutting from 1m lengths):

 Required: 6x1m Long 8mm Threaded Rods (or 5x1m pieces + 1x50cm piece)
 
 Rod 1: 370mm, 370mm, 210mm, ~50mm (The last piece will end up somewhat shorter than 50mm. )
 Rod 2: 370mm, 370mm, 210mm, ~50mm ( Use it for your idler. Alternatively, an M8x30 or     )
 Rod 3: 370mm, 294mm, 294mm, ~42mm ( longer bolt can be used.                              )
 Rod 4: 370mm, 294mm, 294mm, ~42mm (Also, a piece of M8x20 threaded rod can be used        )
 Rod 5: 440mm, 440mm, ~120mm       ( for the wade's/greg's extruder idler.                 )
 Rod 6: 440mm

Smooth Rod Cut Order (when cutting from 1m lengths):

 Required: 3x1m Long 8mm Smooth Stainless Steel Rod 
 
 Rod 1: 420mm, 420mm 
 Rod 2: 406mm, 406mm
 Rod 3: 350mm, 350mm

The Prusa Mendel uses the 4 drivers in the standard Mendel electronics package to drive 5 motors by using two steppers wired in parallel to one driver [2].
