Week 3 - "Home"

The assignment this week was to design a pen and pencil holder.

 Technical Requirements:

• The model is designed and assembled using Fusion 360.

• The model contains at least 2 compartments.

• The model utilized at least one jointing technique (T-slot and/or Bracket with Captive Nut).

• The model is fully designed for fabrication using Laser Cutting (except for brackets using 3D Printing).

• The parts of the model are prepared for fabrication by applying proper fabrication parameters.

• The parts are fabricated and assembled using M3 screws and nuts.

In my work office, I have a Nubian house-shaped pen holder so I wanted to make the pen holder with the same design or idea so it wouldn't be so odd when put together, so the main idea was house shaped holder then I thought of what I want to put in it, so pen and pencils were the base then I add a place for sticky notes as they are always thrown somewhere so they need a place and I started to design that way after sketching I found a space its width fits perfectly the mobile so I build a simple bridge and now it contains a mobile stand.

to laser cut the parts:

• make sure all the parameters is right and the file format is rld.

• put the plywood sheet and fix it with tape if needed.

• open the machine and relocate the origin and check the focus. 

• download the rld file to the machine and frame it to ensure its dimensions and orientation are right and it fits in the sheet.

• close the lid and start the file. 

after cutting all the files you should have now 8 parts and 6 bolts and nuts 3mm (1st pic)

assembling the holder was a bit hard so let me mention the arrangement of the steps:

1. assemble the three inner parts ( the small base and the 2 sides with the t slots) (2nd pic).

2. assemble the front and the back to the slots of the 3 connected parts (3rd pic).

3. connect the body to the 2 outer sides with the X-slots (4th pic).

4. connect all the parts to the base with the t slots (5th pic).

5. last put the bolts and nuts and you made it.

Notes:

•  there is a place for 6 bolts but actually 4 is more than enough.

• if you want to use a bracket the first place you will think of is the middle of the back as it is the larger side and a hidden face to put the bolt but if you do so you should use a captive nut bracket and assemble it to the base part only until you assemble all the other parts and then screw the back part bolt at the very end.

• you could assemble the outer sides to the base first and then put the other parts on it, it will lead to the same result, but I found it easier as I mentioned above.
