🛠️ Print Configuration Overview

Core Printing Parameters

Parameter Recommended Value Notes 
Nozzle Size 0.4mm Standard for most FDM printers 
Layer Height 0.2mm Balances speed and detail; use 0.16mm for higher precision 
Wall Thickness 1.6mm Ensures structural rigidity for the hook and cart 
Infill Density 15-20% Provides strength without excessive weight 
Print Speed 50-60 mm/s Reduce to 30-40 mm/s for the horse head and hook details 
Travel Speed 120 mm/s Minimizes oozing during non-print moves 
Nozzle Temperature 200-215°C Adjust based on your PLA filament's specific requirements 
Bed Temperature 60-65°C Maintains first-layer adhesion and prevents warping 

Support Settings

- Support Type: Tree Supports (recommended)
- Support Density: 10-12%
- Support Overhang Angle: 45°
- Z Distance from Model: 0.2mm
- Key Areas to Support: Underside of the horse's head, the cart's axle, and the base of the vertical key hook

Skirt & Adhesion

- Skirt: Enabled
- Layers: 2-3
- Distance from Model: 6-8mm
- Purpose: Priming the nozzle and verifying bed leveling
- Adhesion:
- Glue Stick (PVP type) or 3D Printing Adhesive: Apply a thin, even layer to the heated bed for maximum grip.
- Alternative: Painter's tape or a PEI sheet also work well for PLA.

Additional Recommendations

- Cooling Fan: 100% power from the first layer upwards to ensure proper layer bonding.
- Retraction: Enabled (4-6mm distance, 40-50mm/s speed) to prevent stringing between the hook and cart.
- Bottom Layers: 6-8 layers to ensure a solid, warp-resistant base.

 

🔧 Assembly & Post-Processing Instructions

1. Post-Processing

1. Support Removal: Use tweezers or flush cutters to carefully remove supports from the underside of the horse's head, cart axle, and key hook base. Take extra care to avoid damaging the fine details.
2. Sanding & Polishing: Use 400-grit sandpaper to smooth any support marks, then finish with 800-grit sandpaper for a polished surface.
3. Cleaning: Use a small brush or air blower to remove any dust or debris from the model.

2. Assembly

This model is designed to print as a single, integrated piece. No additional assembly is required. However, if any parts become loose during handling:

1. Apply a small amount of super glue (CA glue) to the joint.
2. Hold the parts together firmly for 30 seconds until the glue sets.
3. Wipe away any excess glue immediately with a cotton swab dipped in isopropyl alcohol.

3. Usage

- Key Hooks: Hang keys on the horizontal prongs of the vertical hook stand.
- Coin Tray: Place loose change, rings, or other small items in the cart's bowl.
