Vitaminer / Jernvare / Deler som ikke kan printes
Note that additional parts are required for the extruder, although some extruder parts are included in the table below.
Antall | Deler | Kommentar | Leverandører |
---|---|---|---|
83 | M8 mutter (sekskantmutter) | Kjøp 100 for å være på den sikre siden. | |
93 | M8 skiver | Kjøp 100 for å være på den sikre siden. |
|
6 | M8×30 store skiver mudguard / fender / penny washer | ||
2 | M4×20 bolt | For å feste ekstruderen. | |
2 | M4 mutter | For å feste ekstruderen. | |
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. |
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.

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 [1].
