Cavity shown on Chris Bake's YouTube channel: [10 Cell Tubular Resonant Cavity](https://stanslegacy.com/attachments/94)
Single cavity with entry/flow holes at bottom. Accepts 3/4" (19.05mm) and 1/2" (12.7mm) stainless steel tubes. Nuts recessed are sized for 10-32" stainless steel nuts, and 10-32" stainless steel (18-8) set screws. Top accepts 1/2" long 10-32 set screws, bottom accepts 5/8" long 10-32 set screws. Holes are sized for 10-32 tap to thread if desired. 3D filament is regular PLA. Should only need 1 spool of filament, as all prints were done at 50% infill.

[hex resonant cavity with flow holes .stl](https://stanslegacy.com/attachments/68) [](https://stanslegacy.com/uploads/images/gallery/2022-10/FgVmE4XrKZZQeDMI-image-1667233965315.png)Base plate that accepts 10 of the single resonant cavities above. The cavities outer body will need to be filed a little to provide press fit into the below plate. Holes on the outer edge are for 6-32" tap if so desired to prevent resonant cavity from coming out if loose fitting happens.
[WFC base plate v1 v0.stl](https://stanslegacy.com/attachments/74) [](https://stanslegacy.com/uploads/images/gallery/2022-10/ZZbO7Ukfmjiq52DL-image-1667233980842.png) Depending on the vessel diameter used, the base plate may need to be reduced in OD. I accomplished this with a bench grinder and sandpaper. Needle nose pliers are helpful in tightening connections. A 10-32 tap was run through holes that set screws go into. Connect two in series at a time for easier construction/wiring. The OD diameter of the base was intended for the 5.75" ID acrylic tube I used. However, any clear vessel or bucket can be used for testing. Nothing specific for the base being 5.75" OD. The 3/4" SS tubing needs cut to a length of 3.00" 10 qty total needed (total length of 30.00" minus blade width for 10 cuts, approximately 5/8", need 31" total)As of 12/01/2022 above supplier has 36" length for $21.71
The 1/2" SS tubing needs cut to a length of 3.50" 10 qty total needed ( total length of 35.00" minus blade width for 10 cuts, approximately 5/8", to 36" total)As of 12/01/2022 above supplier has 36" length for $37.34
Many methods for cutting can be used, whichever is available to the builder.As of 12/01/2022, PLA filament is $20.00
20 qty, 10-32 SS nuts ($0.08/ea)= $1.60
10 qty, 10-32 x 1/2" SS set screws ($0.17/ea) = $1.70
10 qty, 10-32 x 5/8" SS set screws ($0.20/ea) = $2.00
As of 12/01/2022 above supplier has SS wire for $7.99
With the itemized list above, the cost to print/assemble this cell is approximately: $92.34
