Build your own spheres

Post by yankoch » Mon Dec 31, 2018 4:31 pm

Hi,

Here's a small gift. This is how I build my own inexpensive spheres (less than 10€):

They are very accurate and you don't cry when they fall down.

Use MTN94 matt white: the best and the cheapest.

I usually combine them with the official 145mm spheres I bought on the Laserscanning shop. These surveyors spheres have a perfect centering of the magnet which allows the use with prisms or stickers.

Kind regards,

How solid are these spheres? We use styrofoam, but after a couple of drops they end up looking more cube like than spherical. Are they a few mm thick? Or like egg shells?

Hi,

The material is acrylic. They are quite thick, but they can easily break if they fall down.
But as the sphere costs less than 3€, it doesn't really matter.
I built about 10 spheres and only broke 2. I could re-use the magnet and the washer.

These spheres are accurate and I get very good results in Scene.
Kind regards,

We also make our own sphere's with:

From simple ABS plastic we turn a adapter on the lathe and attach a magnet on the bottom.

Works very well and is about €6 per sphere :)
