Week 3- Journal

Designing Pens and Pencils Holder

Idea of the assinment

Designing a pen and pencils holder consist of many wood parts

Inspiration

consists of two parts one for brushes and the other part is for different typs of pens and pencils.

Software

Fusion 360

using fusion 360 for designing the product parts and smiulate the final result before fabrication.

RD Works

Using rd works to prepare files for laser cutting

Tools and Machines

Prusa mk2 machine is used for 3d printing

PLA filment

Elmalky laser cutter is used for laser cutting process

3mm ply wood is used laser cutting

Step 1

Rule 1# After opening make a new file and save it.

Step 2

Rule 2# Make a new component.

Step 3

Start a new sketch on the left plane

Step 4

Then start drawing the sketch of the side of the holder by draw a rectangle. the rectangle is the highlighted one

Step 5

The rectangle size is 60*80mm

Step 6

Add extentional rectangle for x slot

the rectangle size 6*100mm.

Rebeat the same thing in the other side.

Step 7

Inside the extentional rectangle draw another rectangle its dimentions 3*50mm

Step 8

For the T-slot , draw a rectangle its size 8*3mm then add point in the middle of one of the smallest side.

Add a point in the middle of bottom line of the side.

Step 9

use horizantel and vertical constrains with points to make the t-slot rectangle in middle of the side

Step 10

then use conciden constrin to put the line of the t-slot rectangle in the same level with side bottom line.

Step 11

draw a rectangle its size 5.50*2.40mm and put a point in one of its horizantal line.

Step 12

use horizantel and vertical constrains with points to make the t-slot rectangle in middle of the side

Step 13

use dimentions tool to make the hight of the nut rectangle from the botom line of the 3mm.

Step 14

then add the taps by drawing a rectangle its dimentions 10*3mm and its dimention from the center of the t-slot 3mm.

Step 15

Rebeat the last step to make the other tap.

Then finish sketch.

Step 16

Extrude the side for 3mm

Step 17

After that back to the main component and make a copy with paste new to make the other parts of the holder.

Step 18

After coping a the second part of the holder we will add a finger tap in the upper line for its sketch. its dimention will 80mm/3 *3mm

Step 19

Rebeat the last step on the other side. and add extentional rectangle for the x-slot part.

Step 20

Then finish the sketch and exxtrude the finger taps.

Step 21

Copy the component with paste new then edit the sketch of the new component to make its dimention 50*100mm.

Step 22

Edit the X-slot to be on the upper side.

Then finish the sketch and extrude it for 3mm

Step 23

Activate the main component then copy the third side with paste new then add joints between parts.

Step 24

Add the capative nut bracket. and its degree from 60 to 90 and make it 15*15mm.

we design the capative nut bracket in week3

8- Bracket Connector.mp4

1- Upgrade the Bracket Connector.mp4

Step 25

Joint the bracket to the holder side.

then copy the holder side with paste new.

Step 26

Extrude the x-slot part to make the side with no open parts

Step 27

copy the baracket and joint it to the oppesit side

Step 28

Make a new component and start a new sketch on one of the finger taps then project the middle taps and screw holes

after that draw a rectangle its dimention 37*80mm.

Make the rectangle on the middel of the taps.

Then draw acircle inside the rectangle its diameter 15mm

copy the circle for 4 times.

Step 29

Finish the sketch and extrude it.

then add joints between brush holder part and the sides

Step 30

Project the screw holes on the sides

Step 31

Make a new component

Then starts a sketch on one of the bottom taps.

Then project all the bottom taps.

After that draw a rectangle its dimentions 102*92mm.

Step 32

Draw screw holes between each 2 taps the diametre of the hole is 3mm

Step 33

Extrude the base panel.

Make it Ground and joint all parts to it.

Preparing Parts for Fabrication

First we will choose the bracket and save it as mesh.

From the menu we will choose STL Binary

and for Refinement choose High

In cura we will make the orientation of the bracket on its side

Parametres

uncheck the support.

layer hight 0.3mm

Infill 10%

Printing temperture 215

To prepare wood panels

choose the panel and from create choose DXF for laser cutting

Make laser kerf -0.15

Rebeat the last step with all wood panels.

Then open Rd to prepare the file for cutting

Cutting parametres

Speed 40

Power 50-55

Fabrication Stage

Download the laser file on the laser machine.

then Start to cut it.

Copy printing files with g-code to the printing machine via SD card.

and start printing.

Start assembling the parts by attache the screw and nuts.

files

DXF Files (side1, side2, side3, side4, side5, brush holder,base panel)

STL file (Bracket)

Overcoming Challenges

the overcoming challenge is the add of the nut into the bracket

I asked Eman the fablab specilist for help and she adviced me to use this tools

Final Project

It helps me now how to assemble parts and panels of the final project and the best way to attach the parts.
