"3D printing" [proof of concept]

It was time for me to put "3D printing" to first use.

Obviously, the fun of "3D printing" is not actually the 3D printing itself. In fact, I would say that reducing the amateur approach to free form plastics to "3D printing" is wrongful use of terminology.


Seeing as if the crank of my awning always just hangs there "freely", left to bang against the wall when windy, I decided to give his situation a go as "3D printing proof of concept".

Design considerations

The distance off the wall was around 9 cm, the diameter of the crank 15mm, so the part had to reflect that in size; obviously, the opening to hold the crank shaft had to be an ellipse with a set back minor diameter to allow for minimal clamp type fixation of the shaft within the plastic object. But also, rounded protrusions had to make sure a cheap household rubber could be used to fix the crank shaft into the plastic bit for windy moments.

Proof of concept

So I designed the part in 3D (top left), imported the object into the Maker Bot software (top middle), printed it using ABS (top right). The resulting object (bottom left) was mounted on the wall (bottom middle), where it now serves to hold the crank shaft of the awning in place - EXACTLY as designed.


So that proof of concept really worked well.

One wonders what the future holds once one can see how idea, design and result fit together.
