This week we want to design a multi-use pin holder, like we can use it as a holder for notes and small books beside its function as a pin holder on the office.
So this was my inspiration, because i also wanted to add a mobile holder.
So i decided to make this one but as usual i added some of my personal touches to the design on fusion360.
so let's see how i made this.😌

I used the cad program fusion360 to design the glasses, then i prepared the file of the glasses frame on RD works software to cut it on El Malky ML149 CO2 Laser Cutter, and also used Cura to prepare the arms of the glasses to print it on Prusa

Design/Preparation Process
Design/Preparation Process
1- First i started to draw side 1 of the box:
▪ a rectangle of (110x70mm)
▪ then i attatched two rectangles of (110x10mm) to the sides
of the main rectangle.
▪ then i pointed a mid point in this rectangle's down side to
make a line from this point to the mid point of the main
rectangle's side to make the x-slot.
i repeated these steps on the other side of our main
rectangle.
i also drew a 3 lines on the top of the rectangle to make a different shape for it.
2- Second i drew the t-slot:
▪ first i drew a (2.4x5.5mm) rectangle.
▪ and then a (3x8mm) rectangle and define them by making the
midpoints horizontal to each other.
▪ then i drew two rectangles of (3x10mm) down to make the
taps of this part.
3- Extruding:
from the E shortcut i extruded the first side by 3mm.
finally i coppied this part but after i aded a new component
for it named as (box side1-2).
4- Drawing side 2 of the box:
now i drew the same rectangle of the same dimentions i made the previous steps but the difference was drawing the x-slot up instead of down.
i advice you to make the x-slot smaller than i did when you're using 3mm wood sheet.
also here i didn't add the lines of the shape i made in side 1 to make it different than side 1.
5- I made one copy of the t-slot in this side and then i made a copy of the whole side.
6- I finally pressed E shortcut to extrude this part for (3mm).
7- Here i showed all the bodies to make jointing from these sides to every part as shown.
8- And now here are the parts of the box after making jointing to one another.
9- Here choose the cherry wood from the appearance in the modification tool.
10-Drawing the mobile-note holder:
i started by drawing two rectangle reasonablley to make the hole dimention of the holder (110x100mm).
then i used lines and arcs to complete the holder as shown.
then i drew the t-slot of the holder.
finally i made a fillet to the holder edges only from the inside.
11-Here i finished defining the holder, then decided to make two slots for two taps i will made later in a support pieces for the notes.
12- I extruded the holder then i added the wooden appearance on it.
13- I made a copy of the holder body but in a distance between them almost (62mm).
14- Now i showed up all the parts i made and placed them beside each other to start making projection on the taps' slots and the holes of the screws on the pin holder base.
15- After making the projection of the taps, i started drawing a new sketch in a new component to make the base of dimentions (110x200mm).
16- Here i made fillet of (15mm) for the edges of the base.
16- This is after i made projection for the taps places.
16- Extruding the base for (3mm) then putting the wooden appearance on it.
16- Here i made the supports of the notes as arectangle of (23x62mm) and added the taps of (3x10mm).
16- Then i extruded the supports.
make sure you're putting these supports each one in a new component.
16- After finishing jointings, save the file as DXF from this tool in create toolbar.
16- Before saving make sure you make the (lasr kerf = - 0.15) to make the taps fit easely if you're not sure of the thickness of the wood is exactly 3mm.

Overcoming challenges
Overcoming challenges
The challenge here was in the step of the DXF file exporting from fusion360 and it was that i forgot to make the laser kerf = - 0.15 and this made the places of the taps on the product narrower than it should be
So i advice you to make sure you make the (lasr kerf = - 0.15) before exporting the DXF files to make the taps fit easely if you're not sure of the thickness of the wood is exactly 3mm.
But anyway i overcome this challenge by using sanding tool (i used the flat shape one) to make the taps' places wider to fit in together.
