## Steps
### Step 1: Collect plastic

First, collect all plastic waste from your 3D prints, such as supports or defective prints. Sort the waste by plastic type, such as PLA, PETG, and ABS.

### Step 2: Begin to shredd

At this stage, shred the material and gather it. Determine the number of shredding cycles based on the desired size.

### Step 3: Now it's time for the sheetpress

Now we place all our chopped plastic into the 39x39 in (1x1 m) mold, insert it into the sheet press, and create the plastic sheet.

### Step 4: Time for the CNC

We place our 3.28x3.28 ft sheet, cut into 13.78x13.78 in pieces, under the CNC to create rounded pieces with a diameter of 11.81 in.

### Step 5: Work is done

The final step is to drill the plastic discs and attach them to a metal base to complete the stool.
