Mounts in Seconds
Designed for 15mm wide risers, the +3M/S Riser Mount Compass accommodates webbing thicknesses ranging from 1 to 6mm, fitting everything from thicker lower riser webbing to thin brake pulley webbing.
It installs in seconds without disconnecting your wing and locks firmly in place with a sliding lock and adjustable nylon-tipped set-screw.
Frequently Asked Questions
-
The compass is designed for 15mm wide riser webbing, 1 to 6mm thick. That covers most main riser webbing and many brake pulley sections. If you're unsure of your riser width, we strongly recommend measuring with calipers before ordering.
-
No. It installs directly onto the webbing in seconds using the sliding lock and adjustable set-screw with the included hex key tool.
-
No. The set-screw has a nylon (not metal) tip, so it won't cut or fray riser webbing. Its only job is to prevent the compass from sliding along the webbing, so you don't need to tighten it firmly, just enough to hold it in place.
-
No. It's a fully analog magnetic compass with no batteries, electronics, or charging.
-
It's direct-read: the letter facing you is the heading you're currently flying. No mental flipping or mirroring required.
-
Under 15 grams, lighter than most keychains.
-
3D-printed PETG, a durable plastic chosen for its strength, impact resistance, and ability to hold up to sun exposure and temperature swings.
-
3D printed parts have a slightly different finish than something that comes out of a mold. You’ll see visible layer lines or small surface imperfections, but that’s normal and doesn’t affect strength or function.
Each housing is printed in durable PETG, then hand-finished, assembled, tested, and packaged by me. The result is a lightweight, extremely strong, high-quality part that’s packed with features and built for real-world use.
-
The compass unit, hex key tool, draw-string storage pouch, and a +3M/S sticker.
-
If it doesn't fit, return within 30 days in unused condition for a refund.
-
Absolutely. If you have a friend or family member who flies, the Riser Mount Compass makes a small, practical gift they can actually use in the air. 15mm riser webbing is very common on modern paragliders, but if you’re unsure, it’s worth checking their gear first to make sure it will fit.

I design, 3D print, and assemble each compass in my home office in Northern California.
The 360° globe compass itself is sourced from Taiwan.
