This STL file contains the 3D-printable 20mm conduit clip I designed for routing wiring through my RV-8 project. The clip is sized for 20mm CTPA conduit (available from WireCare) and makes it easy to secure your wiring runs cleanly and safely inside your fuselage, wings or whatever structure you have.

The model is optimized for materials like ASA or ABS for heat and vibration resistance, but can be printed in whatever filament you prefer.

Perfect for RV-series aircraft or any experimental aircraft where you're installing conduit runs.

20mm CTPA Conduit is available from Wirecare.com.  Recommended installation hardware 2ea 1/8 (-4) pull rivets 

This is for just the STL file for you to print yourself.

Material: ASA (recommended), ABS, or any CF variant

Walls: 3–4 perimeters

Infill: 40-60%

STL License & Usage Terms (Applies to All Products)

By purchasing any STL file from this store, you are receiving a personal-use license for your own aircraft project. You may 3D print the file as many times as needed for your individual build, but you may not share, resell, redistribute, or upload the digital file or any printed versions.

Commercial use of any kind is strictly prohibited, including but not limited to:

Selling printed versions of the part

Providing the part or file to others (paid or unpaid)

Using the design in kits, bundles, commercial aircraft projects, or reseller platforms

Posting or distributing the STL in any online repository, group, or forum

Purchase of the file constitutes agreement to these terms.

Liability & Use Disclaimer (Applies to All Products)

All STL files and resulting 3D-printed parts are provided as-is, with no warranty—express or implied. By purchasing, downloading, or printing any STL file, you acknowledge and agree that:

You are solely responsible for selecting appropriate materials, print orientation, infill, print settings, and final part quality.

You assume all responsibility for determining whether the printed component is suitable, safe, and airworthy for your specific aircraft and installation.

The designer/maker assumes no liability for any damages, failures, injuries, losses, or issues arising from the use, misuse, modification, or installation of the part.

These designs are intended for experimental, amateur-built aircraft, where the builder is responsible for all fabrication decisions and safety evaluations.

You must verify fit, function, and durability before installing any printed component in your aircraft.

Use, download, or purchase of any STL from this store constitutes acceptance of these terms.

Because this is a 3D-printed component, performance will vary depending on printer calibration, material choice, infill, orientation, and print quality. Always inspect and test-fit your prints before installing them in your aircraft.
