Project Overview I am developing a functional aerosol accessory for graffiti artists called a Stencil Cap. This device mounts onto a spray can and reduces paint output to allow extremely fine controlled lines for stencil work and detail painting. This is a real physical product that must be engineered for functionality and manufacturability — not just a visual model. Reference images of the concept will be provided. ⸻ Core Product Function The device: • Attaches securely to a Montana 94 spray can • Restricts spray output through a small precision aperture • Redirects excess paint into an attached bottle • Includes internal geometry to control paint flow • Supports attachment of a standard plastic water bottle • Integrates engraved “FREE WALLS” branding ⸻ Paint Capture System (Critical Requirement) The threaded bottle serves as a paint collection reservoir. The design must intentionally redirect suppressed paint flow into the bottle. Internal geometry must: • Guide excess paint away from the outlet • Prevent paint from backing toward the spray nozzle • Allow gravity drainage into the bottle • Maintain stable spray performance Designer should propose appropriate internal channel, funnel, or ridge system. ⸻ Bottle Attachment The design must: • Support standard plastic water bottle threading • Maintain airtight fit • Allow repeated attachment/removal • Be structurally durable Designer should confirm standard bottle thread specification. ⸻ Spray Restriction System The outlet must include: • Precision small aperture for fine line output • Stable airflow geometry • Reduced clogging risk • Ability to modify hole diameter for testing Designer is encouraged to recommend optimal geometry. ⸻ Spray Can Compatibility The rear interface must: • Fit Montana 94 spray cans securely • Align properly with spray valve • Maintain consistent seal and positioning Designer should request measurements if needed. ⸻ Branding Requirement The design must include: • Engraved “FREE WALLS” logo • Clean professional integration • Placement that does not interfere with functionality Logo file will be supplied. ⸻ Deliverables Required Final delivery must include: • STEP file (required) • STL file (required) • Native CAD source file (Fusion 360 / SolidWorks / similar) • Preview renders Design must be suitable for: • Prototyping via 3D printing • Future injection molding ⸻ Ownership & Rights (Mandatory) This is a work-for-hire project. Upon payment: • I retain full exclusive ownership of the design • Freelancer may not reuse or resell the design • No portfolio usage without permission ⸻ Preferred Experience Strong preference for designers with experience in: • Consumer product engineering • Aerosol or spray systems • Plastic product design • Injection-moldable geometry ⸻ To Apply Please include: • Examples of functional product CAD work • Software used • Confirmation you can deliver STEP + native files

Hi there, I understand this is a real engineered product, not a visual concept — it must function, manufacture, and perform reliably in real-world use, including controlled spray output, paint redirection, bottle integration, and clean branding. I’ll design a fully functional internal flow system that redirects excess paint into the bottle, prevents backflow, stabilizes airflow, and supports precision spray control, while ensuring structural durability, repeat usability, and production-ready geometry for prototyping and manufacturing. I’ve recently delivered multiple physical product designs involving fluid control, threaded attachments, sealed interfaces, and production-focused CAD for real manufacturing applications. I’d be happy to share relevant recent work over chat.

As a seasoned designer with a profound command of various softwares, precision is my forte and it's evident in the successful delivery of several projects across the fields of engineering, architecture, and manufacturing design. My expertise in 2D/3D modeling, solidwork and CAD revolve heavily around construction and hydrology, which speaks directly to the functional approach your aerosol stencil cap demands. Having worked on architectural projects that required similar intricate detailing for plumbing systems, I am well-acquainted with the challenges of maintaining stability and gravity drainage while also ensuring an airtight seal - a feat that your product necessitates. My fluency in Autocad, 3d-max and Maya are key strengths to developing airtight geometric structures that guarantee spray control usage while minimizing paint wastage. Moreover, my proficiency spreads beyond the digital aspects of this project. I've had significant experience dealing with real-time objects. For example, I've designed highway projects and worked on interior/exterior spaces which showcases my immersive understanding of material strength and durability - critical factors in designing this stencil cap for repetitive attachment/removal tasks. With me, you aren't receiving just an adept designer; rather an individual merging mechanical insights with the finesse of 3D modeling to give you concrete, tangible deliverables suitable for immediate prototyping and potential future injection molding.

Vutuk Design and Media is ready to take on the engineering and development of your aerosol Stencil Cap project. Our firm specializes in the transition from concept to manufacturable product, offering a full suite of services including 3D CAD modeling, FEA/CFD analysis, and product visualization. We will treat this as a high-precision engineering task, focusing on the critical requirement of the paint capture system. To help us begin the modeling process, we would like to clarify: Beyond the Montana 94, do you want the rear interface to be adaptable for other standard aerosol valve diameters? Regarding the collection bottle, what is the maximum volume/weight of the bottle you anticipate being attached, to ensure structural durability of the threads? Should we include a specific vent hole in the capture system to prevent air-lock while the paint is draining into the bottle? Would you like a high-fidelity 3D animation showing the internal flow path and assembly process for your marketing or technical review? We invite you to visit our company profile and portfolio on this platform to review our successful track record in functional consumer product design. We look forward to a successful collaboration. ?

Am a product designer specializing in functional CAD for injection molding and fluid systems. I will deliver a production-ready Stencil Cap engineered for the Montana 94, focusing on three technical pillars: Fluid Management: I’ll design a conical internal baffle system with a 15° drainage slope to guide overspray into the reservoir, utilizing a "drip-lip" geometry to prevent backflow into the nozzle. Universal Integration: I will implement a PCO 1881 thread standard (industry standard for water bottles) and a snap-fit friction collar tailored to the Montana 94 shoulder profile for a gas-tight seal. Precision Output: The aperture will feature a chamfered exit vent to reduce turbulance and paint buildup (clogging), optimized for 3D printed testing and eventual steel-tool molding. Deliverables: STEP, STL, and Native SolidWorks files. I confirm full IP transfer upon project completion.
