The very first thing that I designed and printed. All of these things are available on Thingiverse.
Then I did this thing. In both cases these were prints that helped me with the printer itself. I also printed a number of improvements designed by other people such as hot bed adjustment wheels and a Z-axis adjuster.
Then I tackled this which was really a large part of the initial motivation for getting a 3D printer in the first place.
This was a spin off from the above as I wanted to mount the encased LCD on the side of the printer.
Then I got onto the theme of organizing things. There was actually a critical piece of work prior to the below, namely some pieces that allowed me to hang a very heavy mirror in our spare bedroom. Not very easy to take pictures of though. The designs are on Thingiverse as a 'Heavy Object Hanger' with the rest of what is shown here. My motivation for that design was not just to hang the mirror but also to demonstrate how useful having a 3D printer can be!
This design was an evolution of the first version from the top of the page.
Another organization thing. This one has also been used under the kitchen sink for a towel hanger and a place to put the washing up liquid.
Yet another organizer thing! And another thing to demonstrate to Sara how useful a 3D printer can be!
One last organization thing. This one for me.
