Furniture Fittings & Knobs
Flat-pack furniture is held together by a handful of small plastic parts, and losing one of them turns a wardrobe into firewood. Nobody sells you a single shelf peg. Printing a set takes an afternoon and costs less than the postage on a spares request that will probably be answered with a discontinued notice.

Common uses
- Drawer and cupboard knobs, handles and backplates
- Shelf pegs, supports and studs
- Cam lock covers, dowel caps and screw hole plugs
- Furniture feet, glides, floor protectors and levellers
- Flat-pack spares: drawer runner clips, back panel clips, connector blocks
- Trim, edge caps and cable ports for desks and cabinets
Where a printed fitting is the wrong answer
Not everything on a piece of furniture is a knob. Load-bearing and safety fittings should be the proper metal part, and we will say no rather than print you a copy: wall-fixing anchors, anti-tip brackets and straps, the bracket holding a wall-mounted shelf full of books, bunk bed and cot fittings, and anything a child's weight ends up resting on. The reasoning is the same every time. A printed part is layered, which makes it strong in the direction it was printed and noticeably weaker across the layers, and it creeps — it gives slowly and permanently under a constant load, which is exactly what a furniture fitting sees for years without anybody looking at it. The failure is silent until it is sudden. The parts we are good for are the ones where failure is an annoyance rather than an injury: knobs, pegs, covers, caps, glides, clips and trim. If you are not sure which side of the line your part sits on, tell us what it holds up and we will tell you straight.
Copying the one you have left
Almost every job here starts with one surviving example and five empty holes. Send us the survivor — or the broken one in pieces — and it is usually enough. The dimensions that decide it are the dowel or peg diameter, the hole pitch (the 32mm system covers most cabinet work, but plenty of makers ignore it), the screw thread on a knob (M4 is the common one), and how deep the socket actually goes. Photograph any part number moulded into the back. We model it, share the file so you can check it against the furniture, and print one to test before the set. And while the file is open, we can change it: a knob shaped to suit your hand rather than the designer's, a peg with a bigger flange because the original always cracked, a foot 5mm taller because the floor is not flat.
Material and finish for furniture
PETG is the sensible default — tough, not brittle, and it does not mind a sunny room. PLA prints crisply and is fine for a low-stress interior part, but it is the one that creeps and goes brittle, so it is a poor choice for anything under sustained load or near a radiator or a south-facing window. TPU is the right answer for feet and glides, where a bit of grip and quiet is the whole point. ASA if the furniture lives in a conservatory or outdoors. On finish, be realistic: FDM leaves layer lines, and a knob is a part your hand is on every day, so it will feel like a printed part rather than a moulded one. A matte filament and a sensible orientation get most of the way; a light sand and a rattle-can gets the rest. We do not colour-match wood or veneer, and we will not claim to.

Furniture Fittings & Knobs — example prices
Worked examples on real models from our print library, priced by the same calculator that estimates your own part. Sizes span small to large so you can see how cost moves with the part.
| Example part | Size | PLA | PETG | ABS / ASA |
|---|---|---|---|---|
| M4 Washer | 12 × 12 × 2 mm | £0.09 – £0.12 | £0.10 – £0.13 | £0.11 – £0.14 |
| Standoff M3x20 | 8 × 8 × 20 mm | £0.35 – £0.44 | £0.37 – £0.47 | £0.42 – £0.53 |
| M8 Washer | 24 × 24 × 3 mm | £0.52 – £0.66 | £0.55 – £0.70 | £0.62 – £0.79 |
| Control Knob (large) | 45 × 45 × 20 mm | £7.89 – £10.08 | £8.25 – £10.55 | £9.02 – £11.52 |
Guide prices for a single unit, calculated from the measured geometry of each example model — not fixed quotes. Small parts land at or near the £0 minimum order, and per-unit prices fall with quantity. Your price depends on your own part, its material and its printability. How pricing works.

Furniture Fittings & Knobs — FAQ
I have lost one shelf peg. Can I get just one?+
Yes, but a set is barely more money. The design work happens once and then each additional part costs materials and printer time — so if one peg has gone missing, print a dozen and put the spares in the drawer, because the next flat-pack move will lose some too.
Can you copy a fitting from a well-known flat-pack brand?+
We can copy the geometry of a fitting you own, for your own repair — that is a spare part, and it is the whole point of this. What we will not do is produce branded reproductions for resale, or copy something that is somebody's registered design and put it on the market. Repairs yes, knock-offs no.
Will a printed knob feel cheap?+
It will feel like a printed part unless you finish it. PETG has decent heft and a matte filament plus a good orientation hides a lot, but the layer lines are there — a hand knows. Sanding and painting gets you to something indistinguishable at arm's length. We would rather tell you that than have you open the parcel disappointed.
Can you print the bracket that holds my shelf up?+
Not if it carries real weight, and definitely not if it is what stops a unit tipping onto someone. Printed plastic creeps under constant load and is weak across its layers. Buy the metal bracket; ask us for the cover that hides it.
How much does furniture fittings & knobs cost?+
There is no fixed per-item rate — price comes from how much plastic the part uses, how long it takes to print, how much support and finishing it needs, and how many you want. The example table above shows what real parts of this kind work out at. Upload your file for a guide price on your own part.
How long does it take?+
It depends on the size of the part, the queue and the material. Tell us your deadline when you enquire and we will tell you honestly whether it is achievable before you commit.
Can I order one of the models from your library?+
Yes. Every model in our print library is a design you can have printed — pick one, choose a material and quantity, and the example price on its page is your starting point. You can also download the file and take it elsewhere; they are all CC0.
Are my files kept private?+
Yes. Uploaded files go to private storage, are never made public, and are only used to quote and produce your job.

What Is TPU (Flexible Filament)?
TPU is printable rubber. It bends, grips, seals and absorbs shock — and it behaves nothing like PLA, which is the whole point and the whole difficulty.
Nylon and Carbon Fibre Parts
The engineering end of FDM. Nylon is tough and wear-resistant; carbon fibre makes it stiff and stable. Both are harder work — here is when that pays off.
How to Copy a Part Without CAD
No file, no drawing, just a broken part and a pair of calipers. That is a perfectly normal starting point — here is how the process actually works.
