Parts made to fit the thing you already have.
Tell us what it has to hold, fix or fit. You get a 3D model you can turn in your browser, every measurement and a fixed price, and nothing is printed until you say so.
From a measurement to a part in your hand.
Every request is designed from scratch around your object, so the first thing you see is the design, not an invoice.
Describe it
Say what it's for and how big the things around it are. A photo with a ruler in it helps more than anything.
Check the design
You get a 3D model to turn and slice in your browser, a measurement sheet and a price.
Confirm or change
Reply CONFIRM to go ahead, or say what to change. Revisions come back the same way.
Pick it up
It's printed, checked and handed over, usually 2–5 days after you confirm.
Designed here, printed here.
Every piece below was modelled for a real object and checked for printability. The price is what one costs in PLA today, printed as designed. Want it sized to your own object instead? That is a $5 adjustment, not a new design.

Folding phone stand
A phone stand that prints already hinged: lift the rest, drop it into one of three notches, fold it flat to carry.

Fridge-magnet bag clip
A chip-bag clip with a living hinge, a sealing rib, a snap catch and two magnets so it lives on the fridge door.

Compliant key carabiner
A key clip whose gate is a printed leaf spring: press it in to open, let go and it springs shut.

Cable comb and tool rail
Rows of compliant fingers that grip whatever you push into them: desk leads in one, screwdrivers and markers in the other.

Caterpillar pen stand
A caterpillar curling round three mushroom cups that hold a slim pen and two spare cartridges upright.

Cloud Raspberry Pi case
A Raspberry Pi 5 case shaped like a cloud, with a soft textured skin and every port where the board expects it.

Fluted desk vase
A tall fluted vase with a bulging shoulder, drawn from a reference photo and printed as one continuous wall.

Raspberry Pi 5 fan case
A ventilated Pi 5 enclosure with a 30 mm fan in the lid, in a screw-down or a snap-on version.

ESP32 dev board case
A small enclosure for an ESP32 DevKitC with a USB opening, side vents and a cable grommet.

Sink-side drain set
An edge rail, drain tiles and a pot rack that turn the counter beside an undermount sink into a drying area.

40 mm corner bracket
A stiff 40 mm L-bracket for M3 screws, oriented on the printer so the corner is as strong as it can be.

Snap-through switch test
A test piece for a two-position flexure switch that snaps between states with no spring and no hinge pin.
You see the part before you pay for it.
A 3D model you can inspect
Orbit it, cut through it and check every opening before anything is printed. It opens in any browser.
Every measurement, written down
Outer size, thinnest wall, hole sizes and each dimension that was assumed, so you can check it against the real thing.
A price in two lines, and a date
The print price comes from the design itself: filament, printer time and handling. The design fee is flat and shown separately, with the ready date.

Two numbers: the print, and the design.
The print price is worked out from the part itself, so a small bracket costs a few dollars and a big rack costs what its filament and hours cost. The design fee is flat and depends on how much is new.
- Filament
- The part's volume printed with 1.2 mm walls and 20% infill, at the material's price.
- Printer time
- $2.00 an hour on the printer, from setup to the last layer.
- Handling
- Setup, cleanup and checking against the measurements at $20 an hour: 10 minutes a job plus about 5 minutes a part.
- Print price
- Those three plus a 15% margin, rounded up to $0.50, never less than $10. Quantity multiplies this line only.
- Design fee
- Added once per request, whatever the quantity. Zero for an existing design; see the three cases below.

Pay for new design work, not for design that already exists.
Every design is built from a library of proven parts, so most requests are a matter of fitting, not inventing.
A piece from this page printed as it is, a reprint, or an STL you already have. You pay the print price only.
An existing design or the proven library parts, resized and rearranged around your measurements. Most requests land here.
Nothing on file fits, so it is drawn from your description. One flat fee, however many revisions it takes.
What a quote looks like, on real designs.
Each one is priced exactly as a request would be today.
Fridge-magnet bag clip
One fridge-magnet bag clip exactly as it appears above. It already exists, so there is no design fee.

Four materials, loaded side by side.
The printer runs up to four filaments in one job, so a part can mix colours or put a rubbery TPU foot on a rigid body.
Stiff and crisp. The default for indoor parts, decor and enclosures.
Softens above ~55 °C · $22/kgTougher, a little flexible, happy with warmth and water.
Clips, brackets, kitchen · $26/kgRubbery and grippy: bumpers, feet, gaskets and sleeves.
Shore 95A · $38/kgHolds up to sun and heat for parts that live outside.
UV-stable · $30/kgEvery design starts from parts that have already printed.
A case is not drawn from a blank screen. The insert pockets, the board's hole pattern, the vents, the lid and the snap fit are all parametric components that have been printed and measured before. Only the shape around your object is new.
Fasteners
Pockets for brass heat-set inserts, screw bosses, captive nuts and clearance holes.
Hole patterns
Raspberry Pi, ESP32, fan, VESA and DIN-rail footprints, with the connector windows to match.
Enclosure parts
Rounded boxes and lids, vent grids, cable grommets, feet, edge clips and slot racks.
Mechanisms
Snap fits, latches, living hinges and flexures that come off the printer ready to move.
Shapes and textures
Fluting, twists, surface textures and organic outlines for decorative pieces.
What it means for you
Fewer surprises. A component that has held a heat-set insert or snapped shut in a finished part does it the same way in yours. When a print report says a part failed, the component it used is marked, and the next design avoids the same mistake.
Faster, cheaper design. Fitting proven parts around your measurements takes a fraction of the time of drawing them, which is why most requests carry the small design fee rather than the full one, and why a revision usually comes back within a day.
Written down. Every design page above lists the components it used and the materials they have been printed in. The library itself is open: 63 components on GitHub, with every parameter documented.

Before you ask.
What can you make?
Holders, mounts, brackets, enclosures for electronics, replacement parts, organizers and decorative pieces. If it fits in a 270 mm cube, or can be split into pieces that join, it can usually be printed.
Do I need a 3D file?
No. Most requests are a description, a few measurements and a photo. If you already have an STL, 3MF or STEP file, choose “Print my file” on the portal.
What does it cost?
Two numbers. The print price is worked out from the part: filament, printer time and handling, from $10. The design fee is flat: nothing for a design that already exists or a file you send, a small fee to fit an existing design or the proven library parts to your object, and the full fee only when something is drawn from scratch. The worked examples on this page are priced exactly as a request would be.
Can I have one of the designs on this page?
Yes. Printed as designed it costs the print price shown on its page, with no design fee. Ask for it sized to your own board, pen or gap and it is adjusted for the small design fee; you see the revised model before anything is printed.
Why is design so cheap?
Because most of it already exists. Every design is assembled from a library of parametric components that have been printed and measured before: insert pockets, board hole patterns, vents, lids, snap fits. Fitting those around your measurements is quick, so the fee reflects the new work, not the whole drawing.
How long does it take?
Most parts are ready a few days after you confirm the quote. The quote gives the estimate for your part.
What if it doesn't fit?
Check the 3D model and the measurements before you confirm, and ask for as many changes as you need. If a printed part still isn't right, raise a “Reprint or fix an earlier part” request.
Which material should I choose?
PLA for most indoor parts, PETG for anything warm, wet or that needs to flex a little, TPU for rubbery parts, ASA for outdoors. Pick “Not sure” and one will be recommended.
Do I need an account?
The request portal asks for your e-mail so it can send you the quote and updates. No Jira licence or payment details are needed to ask.
Measure it, describe it, and we'll draw it.
Requests take a few minutes. You'll get the design and a price back before anything is printed.
