I needed something to house my external SSD. I has a cheap USB3-SATA adapter, so I wanted something which would keep it all together, protect it and be light. All of the others I'd found were solid and heavy. So, I decided to design something to print in flexible filament so that it would better protect the drive.
I printed this in Ninjaflex- which took ages but worked perfectly.
I am very much an enthusiastic amateur when it comes to designing. My designs tend to have two things in common
1) They serve a purpose. I like to design functional objects which have a real-world use. 3D printing for art is fine, but it's its real-world application which will take the technology forward
2) Wherever possible I design to be easy to print and try to eschew supports or complex printing; modifying the design where necessary and possible to achieve this.
