Inspirational picture of the design

Softwares & machines used 

Step (1): I started by sketching the main compartment, so, I started by creating the two mirrored sides .

Step (2): T-slot were added with its right dimensions to the sketch to be used in connecting parts together.

Step (3): Then, I created the other two side.

Step (4): I Created the third side.

Step (5): I added circle with 3mm diameter to place printed captive nut to connect top & side together.

Step (6): creating the partition side that adjusts the compartment size depends on user needs.

Step (7): One of the main used tools is projection tool which used to project sketches & faces to other sketch to avoiding duplication of work, I used it here to project T-slots into the base which is going be used to allocate parts together.

Step (8): creating the base bottom & create slots to add T slot connections to connect all parts with the base.

Step (9): I extruded two sides, then I used the joint tool which used to assembly connect parts together to provide user with assurance that all parts fit each other perfectly.

Step (11): I jointed the 2 sides by selecting origin point on a side then picked the location of the point on the other side.

Step (11): I extruded all parts which extruded by 3mm thickness, which is the thickness of used plywood sheet.

Step (12): After that, I created a full assembly & attaching all parts together to have the final product.

Step (1): I started by sketching the three spinning circles.

Step (2): I added text on each one of them which refers to days number, days names & months.

Step (3): Then, I created the two sides that creates the back & front parts of the calender.

Step (4): I added openings on the front side to shows back circles that includes text.

Step (5): I created a projection for circles to create the spacer parts between calendar circles to provide smooth motion.

Step (6): I used projection tool to create the base bottom slots that would connect all parts with the base.

Step (7): I created the spacer part to creat a small frame.

Step (8): I projected spacer part & circles to add circular frame to hold a small photo.

Step (9): I extruded all parts by 3mm thickness, which is the thickness of used plywood sheet.

Step (10): After that, I created an assembly & attaching all parts together to have the final product.

Assembling is an amazing feature!!!

Step (1): Then, I exported the captive nut bracket as STL file.

Step (2): Then, I uploaded the STL file to Cure to slice it with 0.3 mm layer height, 3 permitter walls & 10% infill density, also sat temperature to 215°C & exported gcode file, the print time was 5 mins & consumed 1 grams of PLA.

Step (3): Then, I exported all parts to DXF files to prepare it for laser cutting machine, I used DXF for laser cutting plugin to export sketches from forms automatically.

Step (4): Then, I exported the DXF files & loaded all files to rhino to arrange them for laser cutting.
