I abandoned the threads holding the buoy halves together in favor of a smooth surface that I will secure with printer resin after installing the magnet.
I printed the halves, and the half that slid over the larger part spread out like flower petals, so I could not print the design like this.
I replaced the smooth sleeve on the top half with three tabs and added support behind the grooves on the bottom. This design should keep everything in shape while I build it.
I printed the tab/slot magnet holder and struggled to assemble it due to floppy tabs. I cured the top half to stiffen the fingers, allowing for assembly with the bottom with the magnet inside. After adding resin around the seam and into the magnet chamber, I removed the excess to create a clean finish. I then cured the buoy while pressing the halves together and dipped the top in resin to seal it. The buoy is now watertight.
When I put the buoy into some water, it was negatively buoyant, as I wanted. The project still needs a feedback mechanism, but I am putting this project on hold for a bit.
I have a Love Sac couch, and I wanted five-inch legs, but the OEM wanted too much. I bought some wooden dowels, but I could not make accurate cuts, and finding the dowel center was a disaster because I did not have the tool. I modeled a collar that should keep my jigsaw aimed correctly, and the hemi-circle at the top will help me find the center.
The rest of the summary posts have been arranged by date.
