Hello everyone ! This is my fourth tank, the Renault B1 bis.
The scale is approximatively the same than my other tanks (~1:18). The model is about 36cm long, 15cm wide, and 16cm tall. It requires 3mm material.
The plans are available on its Thingiverse page .
This model requires :
- 2x Ø3mm 20mm long screws,
- 6x Ø3mm 10mm long screws,
- a huge amount of toothpicks (Ø2mm),
- 2x little zipties,
- 2x rubber bands.
- and some wood glue.
The tracks system is different from my other tanks, it will be much longer to make them. Be patient when you will make this tank.
Enough talking, let's begin !
Step 1: The Body
We begin to make the main part of the tank. Just stack and glue the frame and the sheets around it. We will add the details later.
Step 2: The Turret
The turret is not difficult. It is just some sheets glued around a frame.
Step 3: The Wheels
For the bottom and top wheels : There are many wheels, so be patient. Stack all the 9 layers (You can recognize them with the number of dots to know the order) around a toothpick, and be sure that it pokes out from the two sides. You can use the hollow rectangles to make sure all the layers are perpendicular to the toothpick.
For the drive wheel : trap the 20mm screw inside it before hiding the head. It will be easier to fix the wheel on its support now rather than later.
Do not mistake the parts that are identical with the front wheel (the hole is 2mm for the front wheel and 3mm for the drive wheel).
For the front wheel : Same than the bottom wheels.
Step 4: The Sides
It's important you already made the wheels before this step.
These are the sides of the frame that hold the wheels and the tracks. Caution, because of some details, the two sides are not symmetrical (especially the part that will be in contact with the body).
Add the wheel, the rubber bands, and seal it (there is no slot for fixing the external sheet, so be accurate).
Step 5: The Tracks
This part is very long. If school starts in 3 minutes, do this step when you will get home. You just have to glue two hinges on the slats. Add a cut toothpick and glue it on its ends to make the pivot.
Step 6: The Mudguards
Arg ! i did a mistake on the photo ! the slat with a slot must be in the middle, not in the rear hole.
Step 7: The Exhaust Pipes
Just stack every discs.
Step 8: The Details
Note : I added the details before making the tracks, so you don't see them on the photos, but it's not that important.
Haaaa...The best part. This includes the hatches and the rails, and the hook supports.
And the B1 is done ! congrats ! You can now show it proudly on a shelf. Notice this model can not be motorized, but you can still modify the plans to make your own moving tank if you want.
