It’s the standard file format for 3D printing. If you’ve downloaded a model from sites like Thingiverse, Printables or MakerWorld, it’ll usually be an .stl file. Don’t have one? We’re a printing service, not a design studio — but we’re happy to point you at free models for common parts, and any freelance CAD designer on Fiverr or Upwork can produce an STL we’ll then print for you.
Sliced .3mf files get the same instant price as STLs — the slicer’s embedded grams and print time are what we use. In Bambu Studio or OrcaSlicer, slice your plates, then File → Export → Export plate sliced file (or Export all plate sliced files) and drop the result into the uploader. The price tool will show each plate with a thumbnail so you can tick just the ones you want printed; the colours in the file decide which filaments we load. Only project files that aren’t sliced yet, or auto-quotes that come out above £50, fall back to a same-day manual quote.
PLA is the most popular 3D printing material — it produces clean prints with a nice finish, and it’s great for decorative items, prototypes and general-purpose parts. PETG is tougher and more resistant to heat and moisture, making it better for functional parts that need to withstand stress, outdoor use or higher temperatures.
3D printed parts aren’t solid all the way through — the inside has a pattern (called infill) that determines how strong the part is. Light is fine for display items and covers. Standard works for most everyday parts. Strong or above is for parts that will bear loads or take mechanical stress.
Yes — what you see is what you pay. No hidden fees, no surprise extras once you’ve paid. Shipping is priced separately at checkout (free second-class on orders over £40). If we spot a problem with the file after you’ve paid (bad mesh, unprintable geometry, anything else we can’t sensibly fix) we’ll email you and refund in full within 24 hours — no questions asked.

Search engine across most of the libraries above. Best when you know what you want and just need to find it.
Need a custom design from scratch? A freelance CAD designer on Fiverr or Upwork can produce the .stl — we’ll print it once you have the file. Got a sketch or rough idea? Send us a message and we’ll point you in the right direction.
A mix of my own work and prints I produce for other makers and shops. Hover to pause — tap or click any tile to see more recent work.
Build volume, tolerances and materials at a glance. If your part needs something not listed here, email us — most requests are doable, we just don’t stock the exotic stuff by default.
Upload an STL or sliced .3mf and the price tool gives you a firm price up-front — material, machine time and any PETG surcharge already included. That’s what you pay: order, pay through Stripe, we print. (Files priced above our £50 auto-quote cap fall to a same-day manual quote.)
Final price depends on size, material, infill, print time and any post-processing. Three broad tiers cover most jobs:
£5 – £15
Keyrings, clips, brackets, knobs, small signs, fidgets — anything under roughly 50 g or a couple of hours of print time.
£18 – £45
Lamps, letters, line-art pieces, small enclosures, decorative prints. Where the bulk of jobs sit.
£45+
Busts, props, multi-part models, full-size replacement shells, engineering jobs. Quoted individually to the part.
Unsure which tier applies? Upload your STL — we’ll price it in seconds.
We keep both in stock in a good range of colours. For most customer jobs the right pick is obvious once you know the difference:
| PLA | PETG | |
|---|---|---|
| Best for | Display pieces, props, decorative parts, prototypes | Functional brackets, enclosures, replacement parts that have to take load |
| Strength | Stiff but brittle — snaps under impact | Tough & a bit flexible — shrugs off knocks |
| Heat resistance | Softens around 55–60°C | Holds shape to about 75–80°C |
| Outdoor / sunlight | Not recommended — warps & goes brittle | OK for short periods outside |
| Finish | Matte, easy to sand & paint | Slight sheen, glues well, harder to sand |
| Relative cost | Standard | Around 10–15% more |
Need something else — ABS, TPU, carbon- or glass-filled? Tell us what you’re making and we’ll source what suits. We just keep PLA and PETG on the shelf because 90% of jobs use one of them.
Two machines, picked for different jobs. Between them we cover everyday colour prints, large engineering parts, and awkward materials.
Fully enclosed CoreXY machine with a large build volume, heated chamber and multi-material switching via the CFS unit. Runs custom Klipper firmware for faster, cleaner output than the factory software ships with. This is the printer for engineering jobs, larger brackets, and anything that wants PETG or higher-temp materials without warping.
Fast Bambu-speed bedslinger with the AMS attached for automatic multi-colour and multi-material prints. Perfect for everyday PLA work, colour miniatures, decorative pieces and anything where you’d rather see a finished part tomorrow than three days from now.
You’ve done the easy bit — uploaded a file, picked shipping, paid. Here’s what happens at our end.

Free workshop-authored guides on 3D printing, slicer settings, and printer choice. Worth reading before you upload, or browse the full help library.
Creality K2 specialists. Bambu, Prusa, Ender, Sunlu — FDM & resin. Mechanical rebuilds, firmware rescue, board-level. Mail-in UK from £40.
Klipper with proper input shaper + pressure advance. K2/K1 specialism (we reverse-engineered the firmware). Remote installs from £80, full mail-in overhaul from £150.
Drop an STL or a sliced .3mf onto the quoter and you get a firm price in about three seconds. No forms, no waiting for an email back, no surprise charges at the end. The price you see is the price you pay, and it covers the print itself in the material and colour you chose.
If you upload a raw STL we slice it on our side using sensible defaults for the material — wall count, infill and layer height tuned for a part that actually holds up. If you upload a sliced .3mf from Bambu Studio or OrcaSlicer we honour your settings, so power users stay in control of walls, infill pattern and supports.
The quote covers the printed part in PLA, PETG, TPU or multi-colour, plus basic support removal and a visual check before it goes in the post. Bulk runs of 5 or more identical parts get a discount that shows up automatically in the quote.
Once you confirm and pay, the part goes into the print queue. Turnaround is typically a few working days from order to dispatch, then Royal Mail or a tracked courier across the UK depending on size and weight. Small parts ship in a padded envelope; larger or fragile prints go in a box with foam.
A handful of files will not quote automatically — usually broken meshes, wildly oversized models, or geometry that needs custom support work. If that happens, send the file through contact and we will look at it by hand and come back with a price and a realistic timeline.
Upload your STL or .3mf on this page and the quoter returns a firm £ price in about three seconds. You see the cost per part, the material, and any bulk discount before you decide anything. There is no quote form to fill in and no back-and-forth by email for a straightforward part.
It is the price you pay for the printed part in the material and colour you picked. Postage is added on top based on size and weight. The only time the figure can change is if you later swap material, colour or quantity, in which case you just re-run the quoter.
Yes. We are a mail-in workshop based in Basingstoke and ship anywhere in the UK. You upload the file, pay online, and the finished part comes back by Royal Mail or a tracked courier. There is no need to drop anything off in person.
Some files trip the quoter — broken meshes, very large parts, or geometry that needs hand-tuned supports. Send the file through the contact page with a short note on what it is for and we will quote it manually, usually within a working day.
Typically a few working days from paid order to dispatch, then standard UK post time on top. Bulk runs of identical parts can take a little longer because they sit on the bed for more hours. If you have a hard deadline, mention it in the order notes and we will tell you up front whether we can hit it.
