This is a master listing of freely available STLs, Gcodes and .STEP files formats. For those who may not know, .STEP files are for CNC machining. I personally use PCBWay, if anyone is interested. This will be updated when I design and release more. # 3" Gas Resonant Cavity (aka Hydrogen Gas Gun) ##### The design is centered around market available semi-clear 3" PVC pipe. As of 12-7-25, I've not have CNC machined versions. Until I get around to that, please only focus on the below given STLs. ##### Coming Soon # 9 Resonant Cavity Cell (.STEP files) ##### **Semi-clear PVC pipe (USA - Ebay distributor):** [Semi-Clear PVC Pipe](https://stanslegacy.com/attachments/300) ##### **Main Cell Body: [Main Body-NineResonantCavity\_12-31-25.step](https://stanslegacy.com/attachments/301)** ##### **Electrode Cap: [ElectrodeCap-NineResonantCavity\_12-31-25.step](https://stanslegacy.com/attachments/302)** ##### **Top Plate: [TopPlate-NineResonantCavity\_12-31-25.step](https://stanslegacy.com/attachments/304)** ##### **Bottom Plate: [BottomPlate-NineResonantCavity\_12-31-25.step](https://stanslegacy.com/attachments/305)** ##### **4 Inch Milled Inner Electrode: [InnerElectrode-NineResonantCavity\_12-31-25.step](https://stanslegacy.com/attachments/303)** ##### **Complete Assembly:** [![image-1767202159150.png](https://stanslegacy.com/uploads/images/gallery/2025-12/scaled-1680-/gTzckp0nvlaQjrx3-image-1767202159150.png)](https://stanslegacy.com/uploads/images/gallery/2025-12/gTzckp0nvlaQjrx3-image-1767202159150.png) # Long Tube Cells For Testing (STL files) Coming Soon # Coil Winding Machine (STL files) Coming Soon # Wire Straightener & Length Measuring Machine (STL files) Coming soon. # EPG (STL files) Coming Soon # Steam Resonator ##### The following .STEP and STL files are from Memo WFC 423-DA. The .STEP files have been provided for CNC machining. STLs are for 3D printing. Discrepancies were found with Stan's original dimensions. A 3D printed model was built and the .STEP files were modified to reflect the corrected dimensions. ##### NOTE FROM ETHAN CROWDER: I've used PCBWay's CNC machining services without any issue. Our group is not affiliated with them, nor do we receive any sponsorships for mentioning them. I've provided these for free so anyone in the world with the resources can have the electrodes made. Gerber files for the PCB are provided as a link below.

There are certain individuals that have a habit of taking other's work and claiming it as their own. While I won't name them here, please understand that the .STEP and STL files will probably show up on other websites, possibly for purchasing. The files provided here are FREE OF CHARGE. The original Memo WFC 423 DA diagrams are included for clarity.

Four potentiometer connections have been included for each IC, that allows very precise frequency control. I've use four 10-Turn precision potentiometers. The CD4046's are supplied 12V. This was chosen for easier integration with more modern N-CH MOSFETS, which typically require a gate voltage of 10V minimum for full turn on.** ##### **PCB Gerber .ZIP Folder: [PLL Gated Frequency Generator Gerbers.zip](https://stanslegacy.com/attachments/322)** [![image-1767272306422.png](https://stanslegacy.com/uploads/images/gallery/2026-01/scaled-1680-/KbJEAZOvh7mnnwOb-image-1767272306422.png)](https://stanslegacy.com/uploads/images/gallery/2026-01/KbJEAZOvh7mnnwOb-image-1767272306422.png) [![image-1767272321882.png](https://stanslegacy.com/uploads/images/gallery/2026-01/scaled-1680-/GC5kK0d1LivEwJJ6-image-1767272321882.png)](https://stanslegacy.com/uploads/images/gallery/2026-01/GC5kK0d1LivEwJJ6-image-1767272321882.png) # PC9XB - Variable Pulse Frequency Generator ##### PCB Gerber .ZIP File: # PC9XC - Variable Gate Circuit ##### **PCB Gerber .ZIP File: [PC9XC Gerbers.zip](https://stanslegacy.com/attachments/323)** [![image-1767273180973.png](https://stanslegacy.com/uploads/images/gallery/2026-01/scaled-1680-/tlgD2pastk8DwAxe-image-1767273180973.png)](https://stanslegacy.com/uploads/images/gallery/2026-01/tlgD2pastk8DwAxe-image-1767273180973.png) [![image-1767273415148.png](https://stanslegacy.com/uploads/images/gallery/2026-01/scaled-1680-/ZNqRae6JCxVuIMiy-image-1767273415148.png)](https://stanslegacy.com/uploads/images/gallery/2026-01/ZNqRae6JCxVuIMiy-image-1767273415148.png) [![image-1767273432181.png](https://stanslegacy.com/uploads/images/gallery/2026-01/scaled-1680-/Tze6yRduhILPLL8H-image-1767273432181.png)](https://stanslegacy.com/uploads/images/gallery/2026-01/Tze6yRduhILPLL8H-image-1767273432181.png) # PC9XE - Sequential Gate Circuit ##### **PCB Gerber .ZIP File: [PC9XE Gerbers.zip](https://stanslegacy.com/attachments/324)** [![image-1767273733309.png](https://stanslegacy.com/uploads/images/gallery/2026-01/scaled-1680-/9bhjKCYDq4yDOHXr-image-1767273733309.png)](https://stanslegacy.com/uploads/images/gallery/2026-01/9bhjKCYDq4yDOHXr-image-1767273733309.png) [![image-1767273760109.png](https://stanslegacy.com/uploads/images/gallery/2026-01/scaled-1680-/wWYYfgv05e6nEIWe-image-1767273760109.png)](https://stanslegacy.com/uploads/images/gallery/2026-01/wWYYfgv05e6nEIWe-image-1767273760109.png) [![image-1767273770102.png](https://stanslegacy.com/uploads/images/gallery/2026-01/scaled-1680-/YIULNWoW1fNHpZxO-image-1767273770102.png)](https://stanslegacy.com/uploads/images/gallery/2026-01/YIULNWoW1fNHpZxO-image-1767273770102.png) # EPG - Magnetic Spin ##### **This circuit is currently being revised and tested.
