Great design, I olny wish I have a Swedish furniture store near... the closest one is about 1,500 kms

You can also simply print the scales - I did the same

This looks super! I can't really tell how big it is or how much weight it would support. I have an 80 inch wingspan 24lb model I need to balance. Maybe this could be scaled larger? Thx!

The whole scale is about 20 cm high. You can maybe guess the size from the aluminium tubes - they are 10 mm in diameter. I guess is would be too small and not rigid enough for your model. I used it for ax approx. 9lb sailplane without problems - but I guess 24 lb could be a little bit too much. I don't think that scaling would be an issue if your printer is big enough...

You should add thumb screw holes for the sliders so you can set and lock in the distance.

I initially thought about that, but they came out with a nice friction fit so that I didn't need to. I think I will add that anyway in a V2.

Wish we had something like this for drones.

Thank you for this thing! Thumbs up to you!
