## Steps
### Step 1: Download

The design includes four laser-cut plates, a pipe, and an insert. The files are provided in all necessary formats for local fabrication orders.

### Step 2: Manufacture

The pipe and insert require metal lathe work, which was outsourced to a local fabricator with drawings provided. The plates are laser-cut. The thicker plates support the pipe and insert, and one thick plate secures the insert with a bolt.

### Step 3: Inject the handles

### Injection Moulding Process

**Preparation:**  
Begin by preparing the machine, material, and mould.

**Material Suitability:**  
- PP: Fills the mould effectively.  
- HDPE: More viscous; requires higher injection pressure and is more challenging for this mould.

**Mould Connection:**  
Ensure proper adapter or connection. A sturdy jack pushes the mould inlet onto the injection nozzle.

**Lubrication and Release:**  
Apply lubrication to the insert bit. If cooled too long, the product may shrink and stick. Use rubberized gloves and a twisting motion for release.

**Post-Processing:**  
Clip the injection point with pliers or a knife. Drill a 6-8mm (approximately 0.24-0.31 inches) hole at the end, preferably with a longer drill bit from the inside of the jump rope handle.

**Finishing Touch:**  
For the jump rope, use a 6mm (approximately 0.24 inches) paracord-type rope.
