Plug-on Cage
A cage for the Sennheiser SKP 100, 300 and 500 G4 transmitters. It mounts on the boom pole, so the transmitter does not hang on the XLR alone.

3D printed in short runs. Each one is available as a ready-made print or as an STL file to print on your own printer. All products.

RF antenna guards made of soft TPU. They bend instead of breaking and fit antennas of different lengths. Set of 4.
3D printing
Every product is built layer by layer on a 3D printer. Up close you can see fine lines and texture: that is what gear made in a short run looks like, not something cast in a factory by the million. We do not sand them away, because they do not affect strength or fit. That is what we check on every unit.

We print as many as needed. No warehouse of thousands of units, so no old stock either.
Feedback from sound recordists goes straight into the design, and the next run already has the fix.
Each product is designed for specific equipment: Zoom F8 series, Sennheiser SKP G4, RF antennas.
Rigid material where stability matters, soft TPU where a part has to bend.
Quality control
In 3D printing every unit is made separately, so we inspect each one separately too. A product that fails inspection does not go into the parcel: we print it again.
We mount it on the gear it is made for and check that it holds firmly and nothing gets in the way.
We look for delamination, cracks and under-extruded spots. Anything that could weaken the part ends up in the bin.
We remove supports, strings and sharp edges. Only the layer lines remain — the natural texture of the print.
Electronics are switched on and tested before packing. Guards get bent, and the cage is mounted on a boom pole.
