Custom FDM printing and design support
Bring the problem. Let’s work toward the right part.
A broken component, missing bracket, rough sketch, or unfinished CAD file can be enough to begin. 3D Printing by Kevin helps turn practical problems into evaluated, testable parts for individuals, makers, educators, engineers, and small teams.
What does 3D Printing by Kevin make? Kevin evaluates and produces functional FDM parts such as discontinued replacements, custom holders, brackets, organizers, prototypes, fixtures, and small batches. Projects may begin with a printable file, an existing part, measurements, photos, a sketch, or a clearly described problem.
Two useful starting points
You do not need a perfect file to start the conversation.
The first step depends on what you already have and what the finished part must do.
You have the problem, but not the model
Share clear photos, overall dimensions, connection points, and the job the part must perform. A broken original, sketch, or reference object may help Kevin determine whether measurement, modeling, or scan-assisted evaluation makes sense.
You already have a digital file
Upload an STL, STEP, OBJ, or supporting PDF. Kevin can review basic printability, scale, wall thickness, orientation, support needs, material fit, and whether the design appears ready for a practical test print.
Custom 3D printing services
Built for specific problems, unusual fits, and low-volume needs.
The goal is not to print something merely because it can be printed. The goal is to determine whether a printed part is a sensible solution.
Replacement and Discontinued Parts
Recreate a plastic component that is broken, unavailable, or no longer supported when its function, interfaces, and operating conditions can be evaluated safely.
Custom Mounts, Holders, and Organizers
Build around the dimensions of a particular tool, device, machine, drawer, bench, or workspace instead of settling for a generic fit.
Rapid Prototypes
Turn an early design into a physical object that can be held, checked, discussed, and revised before committing to a larger production decision.
Small-Batch Functional Parts
Produce a limited quantity of repeatable parts when injection molding, tooling, or large production minimums do not make economic sense.
Design and File Refinement
Evaluate existing geometry, adjust practical features, or model a new part around measured requirements and real attachment points.
Fit and Material Evaluation
Compare load, heat, weather, flexibility, appearance, accuracy, and expected use before choosing a material or print strategy.
Project-fit check
A quick way to judge whether FDM printing is likely to make sense.
Final suitability depends on the geometry, material, operating environment, consequences of failure, and available alternatives.
Often a strong fit
- A discontinued plastic cover, clip, spacer, knob, foot, or bracket
- A custom holder, guide, jig, fixture, tray, or organizer
- A prototype that needs fit, scale, or usability feedback
- A low-volume part with no practical off-the-shelf match
- A component that can be tested without creating unacceptable risk
Needs a closer review—or another process
- Parts that support a person or protect someone from injury
- Fuel, flame, pressure, high-voltage, or critical electrical applications
- Medical, regulated, certified, or legally controlled components
- High-temperature or chemically aggressive environments without suitable data
- Very high quantities where another manufacturing method may cost less
Important: A finished print is not automatically a safe or suitable part. Kevin may recommend testing, a design change, a different material, another manufacturing method, or declining the project when the consequences of failure are too high.
A repeatable decision process
The 3D Printing by Kevin P.R.I.N.T. Method™
A useful part begins with the problem and its requirements—not with a random material or printer setting.
Define what is broken, missing, awkward, or worth improving.
Identify load, heat, weather, movement, flexibility, appearance, and risk.
Measure every place the part fits, clips, slides, screws, seals, or supports.
Choose the material, orientation, geometry, and process that fit the job.
Print, inspect, fit, revise, and document what the result teaches.
From first message to tested part
A clear project path without pretending every job is identical.
Share the problem
Send the file, photos, measurements, quantity, intended use, and any deadline that affects the decision.
Review the requirements
Kevin evaluates printability, material demands, safety concerns, design work, and whether FDM is the right method.
Prepare the design
The existing file may be prepared for printing, or the project may require measurement, modeling, and an initial prototype.
Print, test, and refine
The result is inspected against the project requirements. Fit or function may call for a controlled revision.
Help Kevin evaluate the job
The most useful details to include with your request.
Describe the result
- What the part must do
- Where and how it attaches
- Approximate size and desired quantity
- What happened to the original part
Describe the environment
- Indoor, outdoor, vehicle, shop, or equipment use
- Expected heat, sunlight, moisture, chemicals, or impact
- Static load, repeated movement, vibration, or flexing
- The consequence if the part bends, loosens, or fails
Material decisions
The material follows the job—not the other way around.
These are common starting points, not universal promises. Geometry, orientation, wall design, printer setup, and testing can matter as much as the material name.
| Material | Often considered for | Important caution |
|---|---|---|
| PLA | Indoor prototypes, organizers, models, fixtures, and moderate-use parts | Limited heat resistance can rule it out for vehicles, hot shops, or sun-exposed use |
| PETG | Tougher everyday parts, moisture exposure, covers, brackets, and holders | Flexibility, creep, surface finish, and print behavior still depend on the design |
| ASA | Outdoor parts where weather and ultraviolet exposure matter | Requires controlled printing conditions and is not automatically right for every load |
| TPU | Flexible feet, bumpers, grips, guards, and compliant features | Softness, wall thickness, and geometry strongly affect the final behavior |
Practical experience
Repair judgment, modeling experience, and real print testing belong in the same workflow.
Kevin’s background includes industrial machine repair, years of FDM printing and 3D modeling, Shapr3D design work, large-format projects, prototyping, and replacement-part development. That experience supports an observation-first approach: understand the failure, measure the interfaces, choose deliberately, and learn from the test.
Frequently asked questions
What to know before requesting a custom 3D print.
Can Kevin help if I do not have a 3D model?
Possibly. Many projects begin with photos, measurements, a sketch, or a broken sample. The first review determines whether the part can be measured or modeled accurately enough and whether the design work makes economic sense.
What file types can I submit?
The project-intake form accepts common files such as STL, STEP, OBJ, and supporting PDF documents. If a file is too large for the form, provide a secure sharing link and explain what the file contains.
How much does a custom 3D-printed part cost?
Cost depends on design time, part size, material, print duration, support and cleanup needs, quantity, risk, and whether test revisions are required. A simple ready-to-print file is different from recreating a discontinued component from measurements.
Can you copy a broken or discontinued plastic part?
Often, but not automatically. Enough geometry must remain to establish the original interfaces, and the intended use must be suitable for FDM printing. Some parts need redesign rather than a literal copy of the broken shape.
Do you work only with customers in Northern Kentucky?
No. Local projects are convenient when a physical sample or fit check is useful, but suitable digital-file projects can be reviewed remotely and completed parts can be shipped.
How long will my project take?
Timing depends on the current queue, design work, print duration, material availability, quantity, and testing needs. Share a real deadline during intake so Kevin can determine whether it is achievable before the project begins.
Are 3D-printed parts as strong as molded parts?
Not necessarily. FDM parts are built in layers, so material, orientation, geometry, temperature, walls, and loading direction all affect performance. The correct comparison is whether a specific printed design is suitable for its actual job—not whether all printed and molded parts are interchangeable.
The next useful step
Tell Kevin what the part needs to accomplish.
You can begin with a printable file, a damaged original, measurements, photos, a sketch, or a clear description. The first review is about deciding what makes sense—not forcing every problem into a 3D printer.
Submitting a request does not guarantee acceptance. Projects are reviewed for feasibility, safety, scheduling, and fit with the available FDM workflow.
