Here are a couple (or more) of big item prints I have designed.
The tissue box I designed for my own office. The olive green one. Then I noticed a new but bare tissue box out in the music room where my wife provides piano lessons. Thus the white-ish box was born. When she noticed the new boxes, she immediately wanted several more made. Number 5 is on the Mamacetus printer as I write this. Print time per box is over 12 hours.
Next project is what I call a K-cup stackable pod rack. There are three here holding 27 pod cups. Less space by about 1/3 of the rotating wire rack I have been using and holding 3 more pods Another rack on top of these would equal the height of the wire rack. So 12 more pods in the same space. It's also a good excuse to design/print something.
