Downhill Full Suspension Mountain Bike

Santa Cruz V10 - model kit 

This is a 1:9 scale Full Suspension Downhill (DH) Mountain Bike model with working front suspension, rear suspension, rotating wheels and pedals. It is easy to print and assemble and has a lot of realistic visual detail. Fully 3D printed besides 2 spring (optional) for the suspension. 

Based on a Santa Cruz V10 DH S

For this model I tried to focus or realism as best as I could.  All the bikes linkage is accurate to the real one - all freely moving and functional.

Feedback is greatly appreciated!

You will need some glue!

CLEAN BUILD PLATE BEFORE PRINTING FOR BEST RESULTS!! :)

parts - especially on the frame have very tight tolerances!

Frame along with all the functioning linkage is fully print in place with few supports (remove with care!)

Assembly is pretty easy! See steps below -

Both the front and rear suspension uses springs which you can easily find in pens.

Spring Dimensions - 

Front Spring →

•  Diameter - 5mm or less. 
•  Length - 40 mm or less

Rear Spring → 

• OUTER diameter - 5mm or less. 
• INNER diameter - 3.5mm or more.  
• Length - Around 22mm or less (not a defined number - you can experiment!)

ASSEMBLY- (may seem long but don't worry - it's not really!)

Wheels ASSY - 

1.  
   1. Place the wheel alignment guides (2 small blue pieces) into the grooves on one half of your wheel. 
   2. apply glue all around wheel if needed. 
   3. Find the 2nd half of the wheel using the text to match - then place the 2nd half of the wheel onto the first. Ensure proper alignment of the tire tread. 
   4. Keep pressure on the wheel until glue sets - then set aside

      2. Repeat step 1 for 2nd wheel 

       3. On the wheel with the little keyhole on the hub (light blue thing) - slide on the gears - aligning the keyhole.

      4. Slide on the derailleur - in front of the gears. (this will just sit there loosely until we mount the wheel on the frame)

  5. Turn the wheel over and slide on the brake disc. (apply glue if brake disc is too loose) -  set this rear wheel aside 

      6. Slide the second brake disc onto the other wheel. . (apply glue if brake disc is too loose)  - set this front wheel aside 

FORK ASSY - 

      1. Slide the fork stanchion into the fork body. ensure orientation is same as picture.  

1. (the circular side goes in first from the bottom of the fork body). 

2. Slide stanchions back and forth a few times to smoothen its motion. 

   

     2. Press steerer tube into the stanchions until about 16mm of the stanchion is above the steerer tube (refer step 3 picture) (DONT glue just yet) 

   

3.     Slide the longer pen spring into any one of the bottom holes in the fork body. 

   

      4.  Press the fork body caps into the bottom of the fork body. (Apply glue here)

      5. Slide your FRONT wheel in-between the fork bodies - secure wheel by sliding in front axle into place. (any one of the axles). then set aside (ensure the front wheel is oriented such that the brake disc is on the left side of the bike) 

COCKPIT ASSY - 

      1. Slide stem through handlebar till it is in the center of the handlebar. (secure with glue once centered on handlebar)

      2. Slide on brakes - then grips. repeat on other side too (secure with glue if needed)

How it should look - 

SEAT ASSY - 

      1. glue the two halves of the seat together. ensure it lines up properly!

MAIN ASSY - 

PIVIOT ALL the linkage and joints on the frame very gently by hand to loosen them up a little bit.

        1. Slide the whole front assembly we made earlier through the steerer tube on the main frame. - hold in place

  2. Press on the whole cockpit assembly onto the fork assembly to hold it in place. You can apply a small drop of glue here to keep this secure. (Make sure stanchions go around 1mm above the stem (refer 2nd  picture below). 

How it should look - 

      3. Press in bottom bracket onto the bottom of the main frame (may be hard to push in initially) 

      4. - press in pedals on either side. (Apply Glue) ensure opposite orientation. Twist on the pedals to loosen them - the flat part (where you place your feet) should spin independently.

5. Slide the whole rear wheel into place and secure with the rear axle. 

               slide the front circle of the derailleur on the bottom bracket - refer 2nd pic below

  6. slide you second (cut to length) spring into the rear shock guide(in this orientation) - 

      7. Press on the Shock body onto the frame

8.  slide this into place on the frame (refer to picture below) (part of the frame is hidden for clarity)

                  (this may be a little finicky)

               for this I found it easier to first place the exposed end of the spring in place first then the side with the shock guide. 

What it will look like - 

9. lastly - slide in the seat into the seat tube 

Enjoy :)
