Simply put, this is a reusable fastener that can be used as a chest tie, chip bag tie, cable organizer etc. This idea was developed from a previous project where I created a minimal key mount. The shape is a very simple slit shape with two small whole punched out where the rubber light goes through.
In less than an hour of 3D modeling and printing, you will have yourself a simple practical 3D print! I will show two 3D modeling programs (Fusion 360 and TinkerCAD), one of which can be used to create the mount together with the assembly process.
When my school got a 3D printer, I was tempted to print a lot of things I found online, but found that 3D modeling itself was much more satisfying. It's hard to get started and new interfaces are always scary. I put together this tutorial to get someone who knows about 3D modeling and does something useful.
