Watermelon USB Stick Holder

Problem Statement:

Recent analysis by the Staples finance department has concluded that sales for desktop organization products have declined in recent years.  The company would like to ramp up their profits in this area by enhancing the aesthetic nature of these products.  

Your group of two has been hired to design a set of theme-based organizational products.  Your team will design a set of office supplies that are tied together with a common theme. You must be able to justify the theme that connects the products together.  The idea is that the customer will not want to buy just one; they will want to buy the whole set.

        OPTIONS:  
 

• Pen/Pencil holder that can securely hold at least 5 pencils. Cups’ designs must be complex.
• Expo marker holder than can securely hold at least 4 markers
• Tape dispenser that will hold AND cut a roll of scotch tape 
• Utility Box/Dish (paper clips/rubber bands/etc. )
• Phone docking station
• USB Stick/SD card holder
• Anything you can get approved by your project manager!
   

Constraints:

• You will be constructing an actual size model of your product in Solidworks
• Your items must amazing and hard to make
• Your items must contain examples of ALL FOUR main Features:  Extrusion, Revolve, Sweep, Loft 
  • All Features DO NOT need to be present in each piece, just amongst the set
• Your items must take advantage of at least one of: Circular Pattern, Linear Pattern, Sketch-Driven Pattern, Mirror 
  • All Features DO NOT  need to be present in each piece, just amongst the set
• ALL of your items must take advantage of Filleting and maybe Chamfering
• Each piece you design should fit within a 10cm x 10cm x 10cm cube, or 1000cm3 volume equivalent.
  • Each item can be multiple pieces to be assembled for easier printing
  • Maximum length in any direction is limited to 20cm (slightly negotiable, MAYBE 27cm max)
• Should be 3D printable with limited/no supports, (each item can be multiple assemblable pieces to help this)

Summary:

Have you ever had a bunch of USBs laying around with nowhere to put them? Or do you have a boring old USB holder? Fear no more! Here is a 15x7x7 cm watermelon slice that can hold up to 10 USBs! With easy assembly, you will find that this watermelon is an awesome addition to any office setup. This is one part of a set of office supplies on which I worked together with @Samantha_Hum_2508051. You can find the other two parts of the set on her page, along with a Pineapple pencil holder on mine.

Assembly:

To attach the rind to the body, align the corners and glue together

To add the seeds, insert the seed sleeves into the holes in the body, making sure the pocket is facing out on each, and glue.

Design Choices

Seed placement:

For the placement of the seeds, when we just mirrored the seeds from one side to the other, the top 2 seeds created holes that went all the way through the watermelon, as it was so thin on top.

Instead, we staggered the seeds and added one to the middle, so there were no more problems

Seed sizing:

After printing out all the parts, we realized that the seeds were not fitting into the slots that were cut out for them in the body. So, we extended both the length and width of the slots by 0.1cm each.
