STLs ; Gcodes ; .STEP Files

I've provided extensive CAD dimensions of replications from photographic analysis of estate photographs. 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.

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.

Steam Resonator (Memo WFC 423-DA)

The PCB replica is provided below. All components are through-hole (THT) in this revision. Unfortunately, the winding ratios aren't provided in the WFC 423-DA. Experimentation will be required. 
A circuit analysis document will be coming a later date.

CD4046 (Phase Lock Loop) Based Gated Frequency Generator

NOTE FROM ETHAN CROWDER: This is a simple square wave oscillator, with close to a fixed 50% duty cycle, that utilizes two CD4046 Phase Lock Loop ICs. 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.
