Figure 1: <\/span>
\n<\/span>We have started to draw a sketch of the frame in SolidWorks. The length of the arm is approximately 20 cm. We used this dimension for the length of the frame.<\/span><\/p>\n

Figure 2:<\/span>
\n<\/span>According to the weight, we want to make the frame as light as possible. First, we wanted to use a 1 mm thickness, but the frame will not be strong enough when you print it. We adjust the thickness to 2 mm. To make the frame more solid, we used an extra reinforcement in every corner and extra ribs for the straps.<\/span><\/p>\n

Figure 3:<\/span>
\n<\/span>For making it possible to print the frame with the Ultimaker, we had to devide the frame in three parts. <\/span><\/p>\n

Figure 4 (the gears and roll bearings are not drawn yet):<\/span>
\n<\/span>To make the 2 coordinate system, we are going to use gears connected to stepmotors (1). On the other side (2) we are going to use an axis with a roll bearing and a gear, to guide the system. <\/span><\/p>\n

Following are the reasons why we\u2019re using this system:<\/span><\/p>\n
