Tool for paragliding lines measurments

Here are two very handy tools if you measure your paraglider lines yourself, for example using we-measure.io.

1. Weighted Target

The first tool is a pulley combined with a target that you can attach to a table or any other flat surface. By hanging a 5 kg weight from a string attached to the target and passing it through the pulley, you can take your measurements with the target perfectly aligned with your laser and with exactly 5 kg of tension on the line.

💡 Tip: The target should be printed using a white, matte material for the best accuracy.

2. Leica Disto D2 Accessories

The second model is a set of tools designed for the Leica Disto D2 to make measurements much easier. I updated it from the first release.

• Video demonstration: Watch here

• Line Hook: I added a hook to the bottom of the rangefinder to easily grab the line attachment loops.

• Pneumatic Remote Shutter: To prevent the rangefinder from moving and missing the target when pressing the button, I designed a remote control that triggers the button when you blow into a small tube (a clever idea from JC!). I used a standard 3/5 mm drip irrigation tube.

• Alternative Option: Instead of blowing into the tube, you can connect a squeeze bulb to the other end and fill the system with water.

🖨 3D Printing & Assembly Notes

For the pneumatic/hydraulic systems to work, your prints must be completely airtight. I updated it from Sunlu TPU 95A to siraya tpu flex black 85 shore A, the result is way better. with the following settings:

• Infill/Wall Overlap: 25%

• Embed Wall into Infill: Activated

• Wall Generator: Arachne

• Extra Restart Distance: 0.1 mm

• Flow Ratio: 1.05

Additional Tips:

• Sealing: With this Siraya tpu, the .3mf file and the filament profile provided, your print should be perfectly hermetic, however if the finished print isn't fully airtight, you can use a bit of flexible glue to seal it.

• Tuning the Remote: The air/blow option requires a lot of pressure unless the button is already slightly pre-pressed. For this reason, the .stl file has very tight tolerances. If it presses too hard on the button even without blowing, you can slightly file down or cut the internal bump that pushes the button.
