This is the final result of a project that started 5 years ago. It’s also what prompted me to get back into woodworking, re-learn 3D CAD, and buy a CNC machine. During the COVID isolation I came across a YouTube video of a motion sculpture called Monarch ii. (link: [Monarch ii](https://www.youtube.com/watch?v=ZfBsNsWvvJw&t=2s)). David C. Roy is the artist and, if you haven’t seen his work, I highly recommend checking it out ([woodthatworks.com](https://www.woodthatworks.com/)) – he da man. I found the movement mesmerizing and was fascinated by how it worked. I decided to use it as a project to learn Fusion 360 (I’d had some experience with 3D CAD decades ago). My version borrows liberally from his design (i.e. I copied it!) however, I modified the mechanism to reduce the depth and make it more compact to the wall. All the CAD and CAM was done in Fusion and, since I wasn’t about to cut out all those parts by hand, I bought Longmill Mk II. All the parts were cut out on that machine. I’ve posted some renders from Fusion along with sample CAM screenshot below. I did a prototype in MDF first until I worked out the bugs in the mechanism. The final version is made almost entirely from 1/2” (12mm) Baltic Birch, other than the walnut shaft caps. ![IMG_6794](https://forum.sienci.com/uploads/default/original/2X/2/2e8218e12b045c7909a4ce4570ddbdaeb10cf37f.jpeg) ![IMG_6796](https://forum.sienci.com/uploads/default/original/2X/0/0eee47b6bc24247c3a9bcfa3d9ae3a140ec3fa75.jpeg) ![IMG_6797](https://forum.sienci.com/uploads/default/original/2X/9/90ffc0c70601e2cc9716f9ed0d5a8c9f21d46a69.jpeg) Images from Fusion 360: ![Monarch_Take_II_2025-Nov-02_02-22-52PM-000_CustomizedView15757619668_jpg](https://forum.sienci.com/uploads/default/original/2X/0/0fc1c24463b4a4618462c577d78fba37eccb935d.jpeg) ![Screenshot 2025-11-02 093201](https://forum.sienci.com/uploads/default/original/2X/d/dd75a24e50b7acbe4f893e7a9035b2737fcc3ada.jpeg) ![Motion Sculpure Front](https://forum.sienci.com/uploads/default/original/2X/b/ba0bf5393efb71918b627c6108e23fdef164f3fe.jpeg) ![Monarch_Take_II_Side_View](https://forum.sienci.com/uploads/default/original/2X/6/68397c8bd5b7f93b740f514f1b56ce010514bec6.jpeg) ---
