Description

Last month we needed a cheap orbital shaker with a pid controlled heater and a wide plate. So I decided to build it myself. The whole thing cost about 150$. I will upload some photos soon.

 Here is some details about building process: 
The middle gear has a small slit next to the hole. I inserted a 0.5mm metal foil into the slit, so the motor shaft won't slip easily. 
I put the hole lid on the metal project box and use it as a template to cut two holes on the box for two metal rods, then glued the hole lid to the box.
I mounted 3 ball casters to the top of the box (then noticed that I should have used 4). So I made 2 additional supports (two half-ellipsoid parts) later.

The weakest point of this design is the shaft of the side gears. It would be nice if I could set the fill density of only these parts to 100%.

Materials and methods

Here is the additional materials to build this shaker:

- 1 electric motor ~300 rpm

- 2x 8x22x11 mm bearings

- 4 ball casters

- A metal project box

- 2x 8mm metal rod

- For heater, digital thermostat, heater plate, solid state relay and a thermocouple wire is needed.
