cage for a radiometer model

cults3d

To enhance and safeguard a small radiometer (a type of handmade glass bulb with a mesmerizing spinning interior), I once acquired one from nature and discovered its potential. Several possibilities exist for the bars: 4.8 with the initial version, or 6 with the second iteration. The image featuring the blue shape closely approximates the volume that can fit within the cage. Assembly requires care: if you don't tighten all screws simultaneously, the bars may become crooked. I recommend using nylon screws, M3 x 20. To facilitate assembly, I designed lugs that fit together seamlessly; however, the top ones are less than ideal (insufficient protrusion) and could be improved. A slight gap between parts may remain after assembly, as depicted in the third image. The "hat" section might also be slightly bent. Placing soft materials around the radiometer can help secure it in place.
