I have recently been getting into Arduino, and I think that this will be the next step forward in my engineering exploration. I got a cheap kit from eBay, which came with a wide array of components, resistors, capacitors, LEDs etc. However, the box that these came with was not organised whatsoever, and small components where all mixed up. This made it very hard to find the bits that I needed. Further, the box was so rammed full of components that I could never get it to shut properly after taking bits out, this meant that random components often overflowed, making my dad very frustrated with the mess.
For this reason, I wanted to design a box to organise the circuit components.
This box was rather simple, but served its job well. It was certainly not large enough to carry all of the components, however it made a positive difference, as it served as a good containment vessel for all of the smaller bits and bobs which where previous rammed into the larger box. Unfortunately, when I printed this box the first time, I paused the print overnight so that I could sleep. During the night, my room temperature dropped, and the box section came unstuck from the print bed. This meant that when I resumed the print, the tub was dragged around the printing enclosure, and I had to stop the print. Fortunately, the lid had completed, and I used this lid on the final box. Further, the unfinished tub functioned perfectly well as a little tray to store some of the excess components.
Across these three containers, all of my arduino set is now nicely organised, so that I can easily continue with my electronics projects.
My girlfriend was in dire need of a desk organiser, and for this reason, I decided to design and print her one - further, it is good practice for me to design something that isn't related to rocketry and I definitely plan on designing more objects with real world functionality: mounting systems, brackets, tools etc.
This design is admittedly not too sophisticated, nonetheless, provided adequate challenge for a total newcomer to printing - this was one of my first proper prints after a simple cylinder. The design consisted of four distinct compartments in descending height order, the taller of which being aimed at containing longer items of stationary, pencils, pens, ruler etc. The bottom compartment was an effort to contain the small bits of clutter which littered her desk such as rubbers and pencil sharpeners. I designed an outcrop from the side of the longest component in order to stand her phone or calculator on - however this ended up being slightly too small and the height was also not quite right; if I were to build something like this again then I would likely work on this element of the design as I believe it to be a good idea, but just with the wrong execution. The whole organiser is mounted atop four disproportionately small footers - another element of the design I would likely work on in the future purely for the sake of aesthetic satisfaction.
Overall, this design was a success, mostly achieving its goal, whilst there were a few minor details which I would definitely work on if I were to try and redesign in the future.
Shelley was in need of a phone stand which would enable her to charge her phone during battery intensive calls and thorough video watching sessions...
So I designed her this. The goal of this product was to allow the charging of a phone in a vertical position, accommodating a great variety of lengths of chargers - Shelley's for example was very long, extending a great distance bellow the port of her phone, and for this reason, the base on which the phone would sit had to be positioned quite high - 1 inch to be exact. Once I had the basic structure, I aimed to reduce waste and cut down on cost and material use, through the use of the large holes present in the structure. I positioned these so that they would have no negative effect on the structural integrity or the functionality of the product. The support is required to counteract the moment provided by the phone at an angle on the stand, although in hindsight, the angle and strength of this stand most likely did not need to be so extreme as the angle at which the phone sits on is not too far of vertical; this does however provide a wide base which helps with stability, especially on uneven surfaces.
The print will be PLA with a green finish - alongside some added text - as this is my girlfriends faviourt colour.
I am mostly happy with the result of this print and design, however there are a couple of improvements that I would make for future designs. Firstly, I found through testing the plastic has a rather low frictional coefficient - it is very slippery especially when a caseless phone is mounted. For this reason, I would add walls to the sides of the shelf on which the phone sits in order to prevent the phone from sliding off the edge. Further, I would add a way to route a cable out the back of phone stand - either by removing a large strip of material from the bottom, or by adding a single cut-out in which a cable could be routed. I found that the angle was sufficient, however in the future I plan to use an incremental system in which I can customise the angle at which the stand is attached to the main body; this would be through the use of a system which locks, when a load - a phone - is applied.
