---|---|---|---|---|
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 |

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 |
