Your spec. Our printers. Done right.
Custom carbon-fiber composite tooling, fixtures, and replacement components — engineered for manufacturers who need it done right, and shipped from Cartersville in five to seven business days. No minimum order.
The bracket your supplier doesn’t make. The fixture your machinist won’t quote.
Most manufacturing problems aren’t solved by a catalog or a machine shop. They’re solved by a single-quantity bracket, a one-off jig, or an obsolete replacement part — work too small for a CNC quote and too specific for an off-the-shelf solution.
Everhaven exists to close that gap. We design and produce custom parts in carbon-fiber-reinforced composite on industrial-grade additive systems, with the dimensional discipline of an engineering shop and the lead times of a service bureau. Send a drawing, a sketch, or a photograph with dimensions. We’ll send back a part you can put to work.
Four areas where additive earns its keep.
Our work falls into a handful of clearly defined categories. Most of what comes through the studio looks like one of these.
Jigs & Fixtures
Vise soft jaws, locating fixtures, drilling guides, assembly aids, and inspection gauges — engineered to your part and your process.
See examples
Replacement Parts
Discontinued knobs, gears, bezels, brackets, trim, and consumables — reverse-engineered from a sample or produced from your drawing.
See examples
Sensor & Equipment Mounts
Brackets, enclosures, and adapters for cameras, barcode scanners, proximity sensors, instrumentation, and shop-floor displays.
See examples
Custom Tooling
Part nesting trays, kanban bins, shadow boards, workholding, and shop-floor organizers — with embossed labels and part numbers.
See examplesA short list of who we work with.
We’ve found a natural fit with manufacturers and shops across the industrial sector.
Four materials. Production-grade. Engineered for the floor.
We standardize on a focused materials library. Fewer variables, more dimensional discipline, predictable outcomes.
PETG CF
Stiff, dimensionally stable, chemical-resistant. The standard choice for functional parts that need to look engineered.
PETG HF
High-flow chemistry tuned for speed. Used when volume and lead time matter more than absolute stiffness.
ASA
UV-stable and weather-rated. The standard choice for anything that lives outside or in direct sunlight.
PAHT CF
Maximum stiffness and heat resistance. Specified for engine-bay, near-heat, and high-load structural applications.
Custom material qualifications available on request for production programs.

Send a drawing
STEP, STL, IGES, PDF — or a photograph with dimensions. Whatever you have. We’ll work from a napkin sketch if that’s where the part starts.
Receive a firm quote
A line-itemed quote — with material, lead time, and tolerances — back to your inbox within one business day. No surprises and no minimums.
Parts on your dock
Shipped or available for local pickup in Cartersville. Five to seven business days for most jobs — rush available when production stops for you.
What manufacturers say after the first job.
"We needed a replacement bracket Monday morning — the OEM part had a six-week lead. Everhaven had a quote that afternoon and the bracket on our dock Thursday. Fit on first try."
"The drilling guide cut our fixture time from 90 seconds to under 20 per part. We run it on every shift. Small part, real money."
"Called on a Friday with a worn sensor mount that was stopping a line. Part was in our hands Monday. We've been on a standing order ever since."
