We construct and design the levers and holders for a Five Link Mechanism

The most difficult is design of a hole for servo shaft. We made it by drilling of  some amount of  0.8 mm diameter holes. We use servo s9g. The shaft of s9g is 20-tooth gearwheel. We drill 21 hole of diameter 0.8 mm, the radius of the guide circle is 1.87 mm. Here You can see

If You have other than s9g servos, You have to rearrange the 21-hole figure.
And we made servo holders
