Here is my final USB! All done and dusted. I feel very happy with the overall product. I have enjoyed this project and learnt many skills that I will use again. I feel more confident on Pro Engineer and the laser cutter. I have learnt to take my time with a project and how to organise my time more productively (i.e, don't leave everything till the last minute!) I will also spend time getting wood and other materials to the highest quality finish i possibly can, it makes a big difference!
