RepRapable Recyclebot V5 from Recyclebot

Introduction

This page is a work in progress as I go about building my own machine and documenting it in detail.

This is a guide based on the RepRapable Recyclebot V5 from Michigan Tech's Open Sustainability Technology Lab which can be found at:

This project is based off a guide found at:

Acknowledgements

I do not own any of this material. It was published Open-Source online and I am contributing to the previously made guide from Aubrey L. Woern, Joseph R. McCaslin, Adam M. Pringle, and Joshua M. Pearce.

Bill of Materials

I will eventually be creating an updated Bill of Materials.

Electrical BOM

Mechanical BOM

3D Printed Parts

Printed at 0.2mm layer height with a 20% infill and wall thickness of 1mm. I printed every part without support except for small and large pulley.

The Build Guide

Extruder Assembly

Feet

Required Parts/Tools
Wood Frame (2"X8"X4')
(4) M3x16mm Screw
(4) M3 Hex Nut
(4) M3 Heat Insert
(8) #6x1" Wood Screw
(4) Board_Feet (Ninjaflex)_x4.stl
(4) Board_Feet Screw Mount_x4.stl
Soldering iron
Electric drill
Drill bit (Whatever size for woodscrews)
Allen Key Metric # 2.5

I had already performed these steps before starting filming

  1. Insert the (4) heat inserts into the (4) ninjaflex feet
    • Use the soldering iron on the center of the insert in small bursts until the insert is flush
  2. Insert a M3 hex nut into the hexagon cutout of a foot mount
  3. On the opposite side of the foot mount, with your 2.5 allen key screw in a M3x16mm screw through the nut until it is tight
  4. Repeat until all (4) feet are assembled
  5. Hold a foot screw mount to any corner of your wood frame and drill a single pilot hole in any hole with a drill bit
    • I forgot what size I used, just use any size slightly smaller than your screw
  6. Place a #6x1" wood screw into your pilot hole and tighten
  7. Drill another pilot hole in the opposite corner to your previous screw on the same foot and add in a second #6x1" wood screw
  8. Repeat until you have all (4) feet screwed into the corners of your wood frame
  9. Screw on your ninjaflex feet using the heat inserts onto the M3x16mm screws to complete your (4) feet!

Motor Brackets

Required Parts/Tools
(8) M5X65mm Screws
(16) M5 Nuts
(8) M5 Washers
(2) Metal Motor Mounts
(2) Extrusion_Motor Template_x2.stl
Small Wood Clamps
Measuring Tape
Electric Drill
13/64" Drill Bit
(2) 8mm Hex Wrench (or 5/16")
Pencil (for marking)

1. Measure the width of the end of the board and find the midpoint, mark it with your pencil.

2. Clamp down the first printed motor template to the end of the wood frame in the middle where your line was made (make sure the edges are flush) then drill out the four holes with your 13/64" drill bit.

3. Measure out 13.25" (13 1/4") from the end of the wood (the same end) and make another marking.

4. Once your markings are set for the second motor template, you need to clamp it down (I looked for the closest straight object to use my small clamps with) and drill the two exposed holes (the other two holes were covered with the clamp).

5. I placed two of the M5x65mm screws into the two holes and snugged them up with two M5 washers and M5 hex nuts just to clamp down the printed motor template.

6. Remove the clamping device and drill the remaining two holes with the 13/64" drill bit, then remove the two M5x65mm screws.

7. Place the eight M5 washers on the eight M5x65mm screws and place them into the wooden base from the bottom (the side with the feet) and then through the printed motor template on the top and screw the template down with eight M5 nuts.

8. Use the two 8mm hex wrenches (or 5/16") (I used one hex wrench and a pair of vice grips) to tighten the eight M5 hex nuts down on the screws, securing both printed motor templates.

9. Once all eight M5 hex nuts are on both templates and tightened, add both metal motor mounts with the angled side closest to the end of the wood base. Lastly, add the remaining eight hex nuts and tighten them to secure the metal mounts.

10. The final order of parts should be: Screw>washer>wood>printed mount>nut>metal mount>nut

Barrel

Required Parts/Tools
(2) M5x25mm Screws
(2) M5 Hex Nuts
Barrel
Barrel Mount/Heatsink
1/2" Wide Kapton Tape

Nozzle
Barrel Insulation
Electric Drill
5/64" Drill Bit
Measuring Tape
Razor Blade
Scissors
#4 or 5/32 Allen Wrench
Vice Grips or Wrench
Sharpie or Pen
Gloves

1. Use a 5/64" drill bit to drill a 2mm hole in the middle of the brass nozzle (I went through the inside)
