I got inspired by the cat in the photo to the left. When We made the cardboard holder, I created a solid shaped one which lacked aesthetics but it helped me set the dimensions required for this one.

Softwares:
Fusion 360 to design 2.5D shapes
RD Works to prepare the deign and set the required cutting data like specifying the size, cutting and scanning regions.
Krita to draw the cat face details.
Machines: El Malky ML1930 CO2 Laser Cutter.
Materials: 3mm wood.

Sketching phase
I started by drawing a rough skitch on paper to estimate the orientation of the parts and the dimensions of them.
On Fusion 360, I started drawing the side (cat shape) by drawing a rectangle with the dimensions I have for it and drew a centreline.
Using the spline, I created half of the cat face and body then mirrored them around the centreline.
I created the tail using the spline as well.
I added the slots for the taps and screws.
I drew the front/back and the base using lines to make half the shape then mirror it around the centreline.
Assembly phase
After finishing the three sketchs, we extruded the desired shapes by selecting the surface without the slots that are cut out. we extruded by 3 mm as this is the actual thickness of the wood sheets that we are going to use.
After extruding the three sketches into new components, I duplicated the side and the front as we need two of each of them.
Using joints, we assembled the 5 faces together by selecting a surface on the a slot and the corresponding surface on the tap.

File preparation for cutting
After saving the three sketches as dxf, we import them in rdworks.
I drew the face details on krita using the vector tools then exported an svg file that is been converted to dxf using cloudconvert then imported into rdworks to be placed on the shape.

Problem 1: The dxf file was distorted.
Solution: Fixed it on RDworks using "Edit Node - break curve" tool and forcing curves to close. We select the line that is distorted then we select the edit node tool. We click on the line then we click on the node that is connecting between the correct line and the undesired ones. When it's marked green, we click on "break curve". We do that for all the nodes that are connected with the undesired line. Finally we return to the select tool and select the undesired lines then press delete on the keyboard.
Technical aid: We faced a similar issue while working on the session activity, rocking chair and Menna explained how to fix it.
Problem 2: File doesn't appear in machine's memory.
Solution: I tried to copy the file several times to the machine but it didn't appear so I assumed that the machine's memory might be already full so I deleted an existing file, a previous file that I have already cut then I tried again and it worked.
