Approximate model of sg90 servo

by Mikael Lövqvist on

I wanted to do some mashups with sg90 servos so I decided to make an approximate model using openscad.
The model was later exported to stl and imported into blender.

When using the difference function it is important to make sure that the surfaces of the operation are not overlapping because this will yield artifacts. So if you want to make a hole using a cylinder trough a cube with the side 10 mm, the length of the cylinder should be > 10 mm to make sure no overlapping occurs.

When importing stl to blender there is no per vertex normals defined so it is a good idea to use the edge split modifier which will fix this automagically in most cases.


The cross type fastener has been updated because I made a mistake with it where the wide part was too short.

Website up and running

Welcome to LED Alert Hackerspace!

The new server is installed, website it up and running and so far some photos have been added to it.
We are pretty sparse with information for now but we will make effort to add information about ourselves soon.

What we aim to have here is information about projects we have done, will do and wish we could do.
Of course we will also share code, tips, schematics, ideas and miscellaneous things here (hopefully) soon.
