Bill of Materials

This is the complete list of required parts to build this printer (Bill of Materials/BOM):

Part name # of parts used USD per part USD total Where is the part used on the printer?
Beam2424-512 10 12.99 129.90 Main structure
Beam0824-192 (4-pack) 6 5.25 31.49 At the ends of the Y-axis, 4 as the main frame supporting the build platform
Beam0824-144 (4-Pack) 1 4.25 4.25 Filament spool holder. This is the part attached to the main frame
Beam0824-128 (4-pack) 8 4.00 31.98 4 under Y-axis and 4 as spacers in the main structure
Beam0824-112 (4-Pack) 2 3.75 7.50 Filament spool holder. These parts extend the holder to make it more sturdy
Beam0824-096 (4-Pack) 4 3.25 12.99 4 as spacers above electronics
Beam0824-048 (4-Pack) 1 2.00 2.00 1 used below the 192-beam for the Y-axis limit switch
Beam0824-032 (4-pack) 2 1.75 3.50 As spacers attaching the Y-axis to the main frame
Beam0824-016 (4-Pack) 1 1.00 1.00 1 tiny spacer to extend the 192-beam so the Y-axis limit switch fits
Hardware Pack (bunch of screws) 1 24.99 24.99 Lots of screws required. Haven't counted them all yet
Linear Motion Shaft D8x496mm 8 13.99 111.92 4 for Z-axis, 2 for Y-axis, 2 for X-axis (these two are cut to 440 mm each)
Linear Motion Slide Unit 8mm (Pair) 11 6.50 71.45 4 for Z-axis, 3 for the carriage on the X-axis, 4 for the build platform on the Y-axis
42BYG Stepper Motor Bracket 4 8.99 35.96 2 for Z-axis, 1 for Y-axis (under platform), 1 for X-axis
42BYG Stepper Motor 5 19.99 99.95 I have used 17hs8401 steppers (57N/cm) on all axes with 5mm shafts for extra torque, but price should be similar
Me Micro Switch 3 2.99 8.97 One homing-switch (minimum position) on XYZ axis
Nylon Pulley with bearing (4-Pack) 2 3.25 6.50 Used on the stepper bracket for the Y-axis. These must be perfectly centered to avoid print-errors!
Bracket P3 (Pair) 2 1.995 3.99 Holds rods for X-axis
Bracket 3x3 (4-Pack) 8 1.75 13.98 4 at the bottom of Z-axis rods, 1 holding the limit switch for the X-axis, 1 holding the print-fan, 2 on X-axis belt
Bracket U1 (Pair) 4 2.00 7.98 At each end of the X-axis, plus one at the end of the Y-axis, One holding tube that feeds plastic from spool
Bracket L1 (Pair) 4 1.25 4.98 Holds the top of the Linear Motion Shafts on the Z-axis
Belt Connector (Pair) 4 1.50 5.98 Two holds wiring from X-axis in place, one holds the belt, one holds the end at the Y-axis switch
Plate 3x6 (4-Pack) 18 1.25 22.46 4 fixes X-axis to main frame, 14 provides spacing at the Z/X-axis bracket, remaining hold bottom plates in place
Plate 7x9 (Pair) 11 2.00 21.95 4 for the corners of the build platform, 6 for the Z/X-axis bracket, 1 holding the Y-axis motor
Plate I1 (Pair) 2 2.49 4.98 Fixes Y-axis stepper to the main axis beams
