Project Description

The Egg-celerator (Hare Force One)

"Why hide eggs when you can launch them? Designed for the ultimate high-speed Easter celebration, the Egg-celerator is a custom 3D-printed masterpiece that blends holiday whimsy with clever engineering.

The heart of 'Hare Force One' is its integrated spring engine: a sophisticated, print-in-place assembly that combines dual springs and the push rod into a single, seamless component. This design choice minimizes assembly while maximizing the mechanical 'snap' needed to deploy eggs up to 10 feet!

Wrapped in an iridescent rainbow silk filament, the launcher transitions through a metallic spectrum—from golden bronze to vibrant spring greens and blues. It’s not just an Easter toy; it’s a high-performance, color-shifting deployment system for the modern Easter Bunny.

Key Features

Tactile Mechanism: Simple manual spring-pull for reliable, repeatable launches.

Aesthetic: Printed in multi-color Rainbow Silk PLA for a shifting, metallic finish.

Performance: Capable of a 10-foot flight path—perfect for indoor target practice or backyard fun.

Eco-Friendly Fun: Designed specifically for reusable plastic or 3D-printed eggs

🛠️ 🛠️ Quick-Start Assembly: Egg-Celerator Hare Force One

Follow these steps to commission your Egg-celerator. Ensure all parts are cleared of support material for maximum velocity!

1. The Core Power Plant

Take the Spring Assembly (the single-piece print containing the dual springs and push rod). Slide this unit into the Receiver housing.

2. Get a Grip

Thread the Handle onto the end of the Push Rod protruding from the back of the receiver. Tighten until secure—this is your primary launch interface.

3. Lockdown the Barrel

Slide the Barrel onto the front of the Receiver. Ensure the alignment is straight to provide a smooth flight path for your payload.

4. Arm and Deploy

Load: Place your 3D-printed or plastic egg into the barrel.

Prime: Pull back on the handle to compress the dual-spring system.

Fire: Release the handle to initiate a 10-foot "Egg-celeration!"

📋 Bill of Materials (BOM)

3D Printed Components:

1x Receiver: The main chassis of the launcher.

1x Barrel: The guide for your egg projectiles.

1x Integrated Spring Engine: A single-piece print-in-place component featuring dual springs and the primary push rod.

1x Handle: The threaded grip for manual operation.

Optional Projectiles: 3D-printed eggs (hollow or low-infill recommended for flight).

Required Materials:

Filament: Egg 16.4g, reciever/barrel 305g, springs/pushrod 160.8g, and handle 9.4g of PLA/PETG.

Recommended: Rainbow Silk PLA for the signature "Hare Force One" iridescent effect.

Adhesive (Optional): Small amount of CA glue (Super Glue) if you prefer to permanently bond the barrel to the receiver (though the slide-fit is designed for disassembly).

Tools Required:

3D Printer: Minimum build volume of [250mmx250mmx250mm].

Support Removal Tools: Needle-nose pliers or a hobby knife to clear the print-in-place spring gaps.

The reciever to barrel may require light sanding to get rid of the seam.  

Engineering Note: This BOM is 100% hardware-free. By utilizing compliant mechanisms (integrated printed springs), the Egg-celerator requires zero metal components, making it fully recyclable and easy to manufacture on any standard 3D printer.
