Starlink Mini is a great fit for mobile setups — overlanding, vanlife, work trucks — but the stock pole mount assumes you've got a flat surface to bolt to. Most vehicle rack systems use 1-inch round crossbars instead. I designed a 3D-printable clamp that bridges the gap.
The mount is now published on Cults3D: Starlink Mini 1-Inch (2.5cm) Tube Mount .
Design goals
I wanted three things:
- Secure enough for off-road. The clamp had to survive highway speeds, gravel washboard, and the occasional unexpected air. That ruled out anything relying on friction alone.
- Works with the stock pole. No modifying the dish or voiding anything — the clamp accepts the Starlink Mini's factory pole stub and uses the original mount bolt.
- Two build paths. Some people have a heat-set insert kit and want a bomb-proof permanent install. Others want something they can print and glue and forget about. Both are in the zip.
The two variants
Heat-press inserts (permanent)
The primary version uses brass heat-set threaded inserts. You need:
- 2× M5 threaded inserts + 35mm flat-head hex bolts (for the clamp halves)
- 1× M6 threaded insert (reuses the Starlink Mini's original mount bolt)
This is the version I run on my own rack. With ASA plastic and 4 perimeters, the clamp doesn't flex even when I grab the dish itself as a handle.
TPU grips (tool-free)
The second variant is a two-piece clamp with TPU elastomer grip inserts glued into the inner clamping faces. The TPU provides vibration damping and a high-friction grip without needing extreme torque on the bolts. Good choice if you don't have heat-set inserts on hand, or if you want to be able to remove the mount quickly without stripping plastic threads.
The TPU grip pieces print vertically with no support.
Printing specs
I recommend printing in ASA if you have it, or another material with solid heat deflection and UV resistance — this thing lives outside, often in direct sun, sometimes strapped to a dark-colored rack that gets hot enough to soften PLA by lunchtime.
Settings that worked for me:
- 0.2mm layer height
- 4 wall perimeters
- 30–40% infill
- No support on the TPU grip pieces (they print vertically)
- Standard support on the ASA clamp if your printer's overhangs are weak
Design choices
The clamp constrains all three axes with a single bolt. The pole notch handles Z and X (it can't slide up/out of the clamp or rotate side-to-side), and the M6 bolt handles Y (rotation around the pole axis). That means you can loosen one bolt, aim the dish, and retighten — no fussing with multiple fasteners to adjust pointing.
