1.3 Objectives:

This project aims to illustrate the interest of table football in mini version.

The mini-ball table is designed as a miniature model of a football match on thefield and includes 2 teams Players of each team will be fastened on the horizontalbars placed in staggered positions, from which players can easily move the playerand put the ball at will.

With this ball table set, people can play 2 people or otherwise it is still very goodto play alone because it will forge the flexibility of the parts.

Each match took place quickly with the kicking changing in many unexpecteddirections between attack and defense, extremely fierce and attractive resistance.Players manipulate the rods to control the figures, using them to hold up, pass or'kick' the ball Games begin when the ball is served through a hole at the side of thetable, or simply placed by hand at the feet of a figure in the centre of the table Acoin toss is usually used to determine which player or team serves first If it is notthe first match or if the ball gets out of play or if the ball suddenly stops out, thenthe team scored last would get the serve after he scores one The term for when theball leaves the table or gets stopped somewhere out of the men-like figures’ reachis dead ball Expert players have been known to move balls at speeds up to 56km/h (35 mph) in competition.

Besides the construction, students are supposed to meet the requirements of thecourse after having finished the prototype of the assigned system in academic andinterpersonal skill terms When participating in the game, you can also practiceskills such as quick reflexes, thereby creating a smooth coordination betweenhands, eyes, and brain.

1.4 Scope and Limitations:

● Limited about the time:

➔ Time is limited so there is not enough time to learn more about the footballtable.

➔ Foosball table is the first model of marbles, so there is no template andexperience to complete the table better.

CHAPTER 2 - SYSTEM DESCRIPTION

2.1 Conceptual Design/ Conceptual Model:

● Small mica plate with 10mm thick.● 12 ball-bearings.

● 6 stainless steel bars.

- Cut a laser small mica plate into 4 pieces used to form the table base and toconnect all the walls together.

- Printing 3D 6 handles.

- Printing 3D 12 football-players.● Phase 2: Drill and create taro

- Drill holes to attach the table legs to the sides of the table.- Create taro the table base so that the screws can be attached.● Phase 3: Decorate the foosball table

- Stick the ball pitch decal on the table surface.- Stick the decal on the sides of the table.● Phase 4: Assemble the table

- The first is to fix the walls together, then attach the base to the walls to fix

the table.

- The second is to attach the player to the stainless steel bars.

- The third is to attach the ball bearing to the cut holes on the side walls.Then, attach the stainless steel bars to the attached ball bearings.

Step 3: Draw each of the elements (table base, 4 sides around, 4 leg-pieces) then

use laser machine to cut it out in mica pieces.

Step 4: Print 3D 12 foosball players and 6 handles by printing 3D machine The

material used for printing is ASA, with the white color.

Step 5: Drill and screw 4 sides around together and also 4 leg-pieces to the backside of the table base.

Step 6: Assemble all the things.

Step 7: Attach players to the rods There are a total of 6 rods, 3 on each side then

insert them to the table and finally attach the handles.

Step 8: Decorate.

2.3 The design:

2.3.1 Function:

When participating in the game, you can also practice skills such as quick reflexes,thereby creating a rhythmic coordination between hands, eyes, and brain.Moveover, with a game that brings thrill, excitement and concentration and effortlike a ball, it also helps players relieve stress after a hard working and studyingday

- Base

 The table base:

The table base is put on 4 legs which is fixed in 4 conners with 2 length sides and 2width sides Its dimension (length x width x thickness) is 630x300x5 (mm) We cutit by using the laser machine The design in laserCAD program is shown below.

With the layer parameters:

Since we use the red mica, we print grass pitch background decal and stick it onplayfield surface to make it more attractive instead of drawing line in it.

We define the position of all foosmen (X for member of team red and O for team blue):

The stainless steel bars:

After assembling, we realize some error:

- The distance between the goalkeeper and the width side is too close (15mm)for it to kick the ball with all its strength.

- When we drill and wrench screws, there is not accurate, so the playfield is notreally fit the space Therefore, the moving is not smooth when playing game.- The bars is not straight.

 The width side (the goal wall):

The 2 goal walls are attached to the ball pitch and side walls by the 4 table base.Their dimension (length x width x thickness) are 113x78x5 (mm) We cut them byusing the laser machine The picture below is the design in the laser CAD program.

With the below parameters when prepare before cutting:

Because we use the red mica and we want to decorate the foosball table, we stickthe wood drain decal on both the side walls and goal walls.

 The length side (the side wall):

The two side wall are made from a flat mica with thickness of 5mm is cut by lasermachine with the length of 640 mm is tiny larger than the length of the footballfield to fit with the goal wall; the width is 113mm.

It has 6 circular holes with diameter is � = 22.5mm for each Ball - bearing is

installed to withstand force, reduce friction and assist with rotation when 6stainless steel bars are inserted to the table.

The parameters:

The ball-bearing:

Each of them has an outer diameter of D=22mm and bore diameter is d=19mm

The completed side wall:

 The legs :

The legs are adjustable legs The purpose is that in case we finish assembling thetable, it has differences between the standard design and the sample, we can adjustit Moreover, when the players feel that the playfield is not equal or too low, theycan adjust so that they feel better If we do not have flexible legs, in case of ourtable, we have to do it from begin again

Each of legs is made from a 10mm mica piece with tapped hole and oneM8x50mm bolt.

 The foosballmen :

The foosballmen is 3D printed by the stratasys F370 machine We download the3D drawing and then use program to adjust the parameters so that foosballmen canfit in our mini foosball table We have 12 foosballmen

The inside � and outside �

The completed sample:

 The handles:

The handles are 3D-printed by the stratasys F370 machine We download the 3Ddrawing in the Internet and then use program to adjust the parameters so that thehandles can fit with the stainless steel bars We have total 6 handles which havedimension:

and

The complete sample:

 Assembly:

- Step 1: Attach one length side and one width side with one leg-piece for one corner by wrenching tightly enough screws from the outside of the two walls Do the same for the three other corners

- Step 2: Wrench four bolts to four leg-pieces.

- Step 3: Put the table base (playfield) in the space created by four walls and above four leg-pieces.

- Step 4: Insert the bars in to the table and attach the player to the bars.- Step 5: Attach the handles and the stoppers to the bars.

CHAPTER 3 - CONCLUSIONS
