air variable capacitor 3d models

These are insulators/isolators for air variable capacitors used in tube radio circuits. More will be added as I need them. These insulators are used in [my modern tube Theremin design](https://github.com/voretaq7/theremin) **Insulator_C-V100P**...

Experimental desig for a air variable capacitor. I tried covering the fins with copper foil, but every small wrinkle causes arcing. ... Need more tinkering :-)

... to fit my specific SHCS, so it may not fit yours. It has a little 6mm hexagon inside to lock it into the bolt head. I uploaded both a bottom mount and a panel mount version. I may post a version for air variable capacitors when I get some. ...

... of the bolt. I made a bottom mount, and a panel mount version. Both have 4mm bolt holes. My variable capacitors use 2.5mm bolts, yours may be different. I will likely make a version for air variable capacitors soon, as I have some in the mail.

Variable capacitor

variable capacitor for old school radio design

This is a variable capacitor, by turning the vertical axle you can change how much the plates overlap, changing the capacitance of the device.

Old school looking (ish) variable capacitor. ...My super ultra cheap Part Tester/LCR meter (probably not at all accurate) gives me a capacitance range of about 25pf to 130pf.

A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically.Dear Guest! If you download this model, hit "like". ...Enjoy :-)I will also be grateful if you give me an idea of a new project you need.

A mostly-printed variable capacitor. I don't necessarily recommend making this one, as I designed it around what I had, and it isn't perfect. This is more sharing for inspirational purposes :) Uses two 100mmx70mm single-sided copper clad...

DIY Butterfly Variable Capacitor thats hard to find these days.

Variable Capacitor Knob for China HF antenna tuner kit.

this is a knob for varicon capacitor for my tuner On ebay: Polyvaricon variable capacitor x10 with mounting screws QRP ATU, VFO, RECEIVER

A variable capacitor based on a "can capacitor" with about 20-70pF. ...Things required: 50mm adhesive copper foil + some small cables 3/8" thread cutter Technical Data: Capacity: Max Voltage: (depends on Filament, print temperature ....) Print Settings...

This is a 3D printed butterfly type variable capacitor. Can be extended to any length/capacity by just adding more plates. Distance between rotor and stator plates is ~ 2.5mm. Currently contain only 3 plates for the rotor and 4 sets for the stator.

I found a need to extend the shaft of those cheap Chinese variable capacitors to make them more useful in my radio projects. So, here it is. You can extend the shaft to your own desired length. It is a good fit on my bag of VCs from China and has a...

Haven't installed the plates themselves for testing of the capacitance yet.*** A variable capacitor designed to be approximately 10-120pF. I have not printed this yet, so it's all mathematical at this point. It is designed to use two 40mmx80mm pieces...

Air capacitor 158-6

Remix of "Air Gap Capacitor System"

Air gap capacitors are so very expensive, so I make my own. This is two end brackets, one set of spacers for anode and cathode, a stencil of anode and cathode plates, and an alignment tool. Most likely best printed in ABS, ASA, or PETG; PLA is just...

I made this variable capacitor as CV trimmer for my magloop antenna project, combined with fixed capacitor made in bakelite pcb. ...It works well for low power transmitting (5 - 10 watt).

A variable capacitor based on copper foil and capton. ...You need to cut the M6 threads Print Settings Printer Brand: Ultimaker Printer: ...

This is OpenSCAD high voltage sliding variable capacitor generator. It allows you to specify number of plates, plate size, distance, sliding gap, etc. To be used inside magnetic loop antenna or antenna tuner. This is based on my positive experience...

This fits the drive shaft of a vacuum variable capacitor that I have. Shaft is ~12.6 mm in diameter (the bore in this part is 12.75 mm). Shaft also has a crossbar thingie going through it which is 3 mm in diameter and perpendicular to the shaft,...

Variable air inlet vane for my 3D printer enclosure. See photo! https://www.youtube.com/watch?v=yqrHjTeFomU WARNING - not for beginners. - very tight fit! After printing needs sanding to get it fit and working! - Need to super glue the ...

Capacitor Button/knob for 1-30Mhz Antenna Tuner variable capacitator

This is a 3d model of a type of variable capacitor (Drehkondensator) I bought at Pollin Elektronik (Germany). Drag this into your project to add e.g. ...holes into your casing.

A model of a 10 kV, 0 - 300 pF vacuum variable capacitor that I have. It's stamped with C.M.C-147-684, which may be a model number. No other markings apart from voltage rating. It was listed as a Jennings cap on eBay, I think. This is not a...
