The First Early Design For Pencil Holder

This week we were asked to make a pencil holder by using a 3D Printer, so the first thing I was thinking about was the design, Despite the first design was good but it was very regular and I want to try new something.

And Suddenly while I was thinking about a new design I found the (sea urchin) structure amazing and inspired me in my design.

Tool Chain

I used 3D Printing for The Pencil holder because it's made of Plastic, and I found it's more suitable for the design, fusion 360 for making the design, also Cura helped me extract .gCode For the design instructions to the machine.

Machine

PRUSA i3 MK2

Software

Ultimaker Cura

Material

PLA Filament

Design/Preparation Process

I Made Three sketches for this design.

Development/Implementation Process

The First Try For Design

The Steps To Make the Pencel Holder In Fusion Was:

Make a 90mm tall clyndrical.

2. Make a 4 mm shelling thickness

3. Sketch for the bubbles.

4. Emboss them in the holder.

5. Make A circular Pattern for the pencil holder.

6. A 2 mm fillet.

7. Make a quarter Circle at the base.

8. Then revolve it around the Z-Axis cylindrical holder.

Final Result wasn't what I want or expected, so I decided to redesign it again based on the sketch below:

The Final result wasn't what I want

The Second Design

In the Next Design, I do the following steps to make it:

Make 50 mm diameter circle

Make an offset plane 15 mm high

Make a 60 mm in diameter circle in the new plane

Loft the two sketches

Fillet the edges with 10 mm

Draw sketch of hexagons in the surface plane of the body:

Make an extruded cut by -20 mm down :-)

The output after extrude

Added some material to the Shape and color :-)

Now time To Save the design for Cura software

Saving as STL (Binary)

The
Result :

In Cura Software

In Cura Software I made:

Profile: 0.2 mm.
Infill: 20%.
Supports : Yes, Touching plate.
Adhesion: No.
Dimensions: 50 × 50.3 × 13.8 mm.

Will take: 1h 27min.

Material: 8 grams.

In the lab

Prusa 3d printer

In the Lab, After send the files to a SD card and insert it to Prusa (3d printer).

1. Insert the SD Card in the 3D Printer.

2. Choose “print from SD” from the menu.

3. Then choose the name of your (.gcode) file, you have named it.

Start Heating the nozzle to print

The machine start to make sure of the dimensions of the plate.

The Beginning of the Print :-)

Here are some Photos of the Printing Process ❤

The Final Output ❤

Community of Learning

When I Was at the Lab Preparing the (.gcode) file to be printed, the lab specialist, Eng. Amany told me to change the Heating for the Filament material to 215 c Instead of 200 c because this is more suitable for the PLA Material we are using, and I didn't know that :-) .

Heating the Prusa 3D Printing to 215 c, not 200 c

Changing the Printing Temperature

Overcoming Challenges

After We finish printing and tried to take the print-out from the build plate the print attached to it because of the heat, so we spray alcohol around it and Eng. amany told me this make it easier to pull it from the build plate, and we succeed :D .
