It was first born on the wheels of a

surfboard and a pair of skates, similar to a surfboard/snowboard with wheels. Compared with the ordinary skateboard, the board is longer and wider, the wheels are larger, softer and wider, and it has longer endurance, better road adaptability, faster start time and better sense of operation. Long plates are usually between 33 and 59 inches (84 to 150cm) long and 9.0-10.0 inches (22.8 to 25.4cm) wide. Main materials include maple, bamboo, glass fiber, carbon fiber, metal, mixed materials and so on

The speed can usually reach (30--120km/h). The current world record is 143.89km/h.It's cool, it's fast, it's exciting

## Step 1:

Put the cuboid on the

working plane, its length 100mm, width 22mm, height 2mm,Suitable length and width of board for best experience

## Step 2:

Use arc to cut out

suitable space, so that the wheels have a suitable installation position.

Put the elbow on the working plane, the width of the outer pipe is 7, the wall thickness is 7, the bending Angle is 60, change to hole. Arc diameter 100

## Step 3:

Move the elbow to the

right side of the cuboid and align with the top of the cuboid. Then move the elbow to the left by 5mm.

## Step 4:

Use alignment and the results are as follows

## Step 5:

Get more arcs quickly.Copy and mirror the bend. The

mirror image is moved to a position symmetric with the first bend

## Step 6:

Combine

the two holes, copy and mirror them to a symmetrical position, and then combine all the graphics

## Step 7:

Punch holes in the proper position to give space for plate bridge installation.

The cuboid is placed on the working plane with a length of 6mm, a width of 6mm and a height of 6mm. Align with the center of the assembly, move 2mm away from the top of the assembly, copy and move to a symmetrical position, and then combine all the graphics.

## Step 8:

Perforation for easy mounting of fixed cylinder

One cylinder was placed on the working plane with a diameter of 1mm and a height of 10mm. It was copied 8 times, 4 of which were changed into holes, 1mm away from the square hole, and then combined with the plate. The remaining 4 cylinders were inserted into the hole with a color of black and the plate with a color.

## Step 9:

Replace

the cylinder with the working plane, 48mm high, 20mm long and 1mm wide, change the hole, align with the center of the plate, then move up 1.5mm and combine with the plate.Suitable radian, easy to step

## Step 10:

Install plate and fix

Put a cuboid on the working plane, 6mm long, 4mm wide and 0.5mm high, align with the top center of the plate, then translate 7mm backward to copy, move to a symmetrical position, and then group with the plate

## Step 11:

Set

the cylinder on the working plane with a diameter of 0.5mm and a height of 1.5mm. Change the adsorption grid to 0.1mm. Group again. Copy, place in place, combine with board.Drilling for easy fixing

## Step 12:

Put

the cylinder in the working plane, 2mm high and 0.5mm in diameter, then put the polyhedron in the working plane, 0.5mm high, 1mm long and 1mm wide, align with the center of the cylinder, align with the height and combine. Copy and move it to the appropriate location.Get the nails for fixing

## Step 13:

Combine

the two screws, repeat several times, move to the appropriate position, and then combine.

## Step 14:

Make an incline. Used for

connecting rods.

Place the complex shape trapezoid in the shape selector on the working plane, 2mm high, 4mm long and 2mm wide. Then the cuboid was placed in the working plane with a length of 7mm, a width of 3mm and a height of 5mm, and turned into a hole. The cuboid was rotated 21° vertically and placed in a suitable position. Then it was combined with the trapezoid and copied.

## Step 15:

Place

the tube in the working plane with a diameter of 1.8mm and a height of 2mm, rotate it until it is parallel to the inclined plane. The tube is made of elastic material for cushioning

Place the cylinder in the working plane with a height of 22mm and a diameter of 3mm, align it with the center of the tube, and then combine.

## Step 16:

Place

the tube in the working plane with a diameter of 1.8mm and a height of 2mm, rotate it until it is parallel to the inclined plane. The tube is made of elastic material for cushioning

Place the cylinder in the working plane with a height of 22mm and a diameter of 3mm, align it with the center of the tube, and then combine.

## Step 17:

Place

the cylinder on the working plane, 1.2mm in diameter and 3mm in height, perpendicular to another inclined plane, move to the appropriate position, copy, and then change to hole, and combine with the cylinder and inclined plane. Move the other cylinder to the right position. Combine with tube. Combine with tube. For connecting rod

## Step 18:

Do

the rounds of .Place the cylinder on the working plane, 3mm in diameter and 8mm in height, rotate 90° vertically and change it into a hole. Position the cylinder with the working plane, height 8mm, diameter 6mm, align and combine the center of the previous cylinder, then change the diameter to 8mm. Make room for ball bearings

## Step 19:

Make

ball bearing so that the wheel can slide freely.

Place the cylinder on the working plane with a diameter of 3mm and a height of 0.1mm. Put the cylinder on the working plane, 4mm in diameter and 0.1mm in height, align with the center of the previous cylinder, and then combine. Copy the assembly, move up 0.3mm, copy again, move up 0.3mm, and combine. Put the ball on the working plane with a diameter of 0.5mm, copy it to 8, move it to the appropriate position, combine, copy, change to hole, combine with cylinder, and then move the solid ball to the appropriate position.

## Step 20:

Place the cylinder on the working plane

with a height of 0.7mm and a diameter of 4.1mm, and copy. Diameter 4mm, change to hole, center alignment, copy to hole, then align with center of cylinder in 9, combine. Leave room for ball bearings

## Step 21:

Bearing and wheel combination

## Step 22:

Copy, mirror, move to the right position, and then combine with it. Combine with rod. Put the cuboid in the working plane, 6mm long, 2mm wide, 3mm high, put it in the appropriate position, and combine it with the gray figure. The appropriate height, so that the center of gravity is low, in order to be able to move at high speed.

## Step 23:

The

front bracket is copied, mirrored, moved to the appropriate position, and then combined with all the graphics.

## Step 24:

The

front bracket is copied, mirrored, moved to the appropriate position, and then combined with all the graphics.
