I am a retired engineer. We recently purchased a winter home. To keep myself occupied I create using my 3d printer. One of my big (actually huge) projects in creating a 3d model of my winter home. It has been very fun and I have learned much about design for 3d printing. I also am learning the finishing process (preparing models for paint and the painting process). I believe that the learning never ends. This has been very rewarding and I look forward to creating more models. Don
