Arc V PRO Strobe Light Mounts for DJI Air 3S Drone

This project contains custom mounts designed in Fusion 360 for the DJI Air 3S drone and the ARC V Pro Drone Strobe Light from Firehouse Technology.

The top mount bracket is printed in Overture PETG Space Gray, while all other mounts are printed with Overture TPU 95A Space Gray. The download package includes a complete 3MF file for the Prusa XL containing all print settings used for this project, including my Overture filament configurations. The PETG top mount bracket prints without supports. The TPU STL files include several print-optimized elements such as a raft, optional PLA or soluble components, and support structures that help achieve clean and consistent results. These helper parts can be removed or used depending on your printer and preferences. Photos are included to show how the different parts of one of the pieces are arranged.

When importing the TPU STL files, make sure to use Split to parts so you can separate all the elements that form the model. In my case, I printed the 0.2 mm layers in PLA and the rest in TPU to minimize tool changes on the Prusa XL. This produces a very clean result, and the supports are easy to remove while leaving a smooth finish. For the mount with the two hooks, there are two 0.2 mm parts that I also printed in PLA. If you do not have a multi-extruder printer, you can simply delete these thin parts and rely on a 0.2 mm gap for the supports instead. It is always best to run a few small tests to find the ideal setup for your printer.

To ensure a perfect fit, I molded the drone arms using silicone putty to capture the exact cross-sections of both the front and rear arms. Two reference photos of the molds and the printed arm profile sections are included.

The full set includes one top mount bracket, one top and bottom mount with hooks, two front arm mounts, and two rear arm mounts. The top and bottom mount with hook is the same model and can be printed once or twice depending on how many you want to use.

Each mount has its identification engraved directly into the model to help place each piece correctly on the drone.

I would also like to mention Firehouse Technology for their excellent strobe lights, and Aerial-Pixel for their well-designed DJI strobe mounts. While I created these models specifically for my own needs and preferences, the work of these companies has always been a great reference point for high-quality drone accessories. If you need professionally manufactured mounts or additional models for other drones, I strongly recommend both companies.

For installation, it is recommended to place the TPU mounts on the drone first and insert the ARC V Pro lights afterward. Once installed, the strobes can be removed easily for charging or activation. The USB port and power button remain accessible even when the lights are inside the TPU holders.

Print instructions

For the Top Mount in PETG, no supports are needed.

• 0.2 mm layer height

• 3 perimeters

• 20% infill (Gyroid)

For the TPU mounts, supports are required for printing, but I designed all support structures directly in Fusion 360 to ensure the best possible results.

• 0.2 mm layer height

• 100% infill with TPU 95A

• PLA or solube supports recommanded
