Electronics & PCB Mounts
Every electronics project reaches the point where a board has to be held in a very specific place and nothing off the shelf fits. Standoffs, rail clips, trays and inserts are small, cheap prints, and once the file exists it scales across the whole batch of units.

Common uses
- DIN rail clips, feet and adaptor plates for rail-mounted kit
- PCB standoffs, spacers, board trays and card guides
- Raspberry Pi, Arduino and single-board computer mounts and trays
- Enclosure inserts, panel blanks, display bezels and button caps
- Cable strain reliefs, dust glands and connector holders
- Bench kit: probe holders, module racks and prototyping trays
What printed plastic does not do for electronics
Three things worth being blunt about before you order. Mains voltage: filament has no electrical rating, prints have porosity and gaps between layers where tracking and creepage can happen, and a part from us must not be relied on for mains isolation, live-part barriers, or anything inside a mains enclosure where someone's safety rests on the plastic. Buy the rated component. EMI: plastic does nothing for shielding — a printed enclosure is transparent to interference, in both directions. If you have an EMC problem or an EMC test coming, the answer is a metal or metallised enclosure, and no amount of wall thickness changes that. Fire: standard PLA, PETG, ABS and ASA are not flame-retardant rated. If a part sits next to something that can get hot, or the finished product has to meet a flammability standard, it needs a material with a proper rating and a manufacturer's data sheet behind it, and we are not going to pretend a printed part meets one it has never been tested against. Low-voltage projects, bench kit, board mounts, and mechanical furniture inside a properly rated enclosure — that is where this fits, and it covers most of what people actually need.
Heat, and where the board really sits
PLA starts to soften somewhere around 55 to 60°C, and a surprising amount of electronics lives above that. A single-board computer under sustained load in a sealed box, a linear supply, a stepper driver, an amplifier, anything with a heatsink on it — PLA standoffs in those places will slowly slump and take your board's alignment with them. PETG is the sensible default. ABS and ASA take more heat again, and ASA is the pick for anything outdoors or in a sunny cabinet. The other heat-related decision is threads: use heat-set brass inserts for any screw that will be undone more than a handful of times, because a printed thread or a self-tapping boss in plastic is good for a few cycles and then it is a hole. Tell us the hottest the part will ever get and whether it is a sealed box, and we will pick around it.
Dimensions, tolerance and what to send
The best thing you can send is a STEP or DXF export from your EDA or CAD package — board outline plus the mounting hole pattern, and we can work directly from it. Failing that, calipers and a photo with a rule in shot. The numbers that decide it: hole pattern and hole size, whether you want clearance holes or self-tapping bosses, the board thickness, component heights on the underside, and the clearance you need around connectors. Typical achievable tolerance is around ±0.2mm, which is fine for a board tray and marginal for a snap fit — so where a fit is tight we print a small test coupon of just that feature first rather than a whole part. Standard interfaces we know: 35mm top-hat DIN rail, M2.5 for most single-board computer patterns, M3 for most everything else. You keep the file, so the second production run does not need us.
How it works

We check printability, then confirm
A person reviews orientation, wall thickness and supports, flags anything that will not print well, and confirms your final quote before any work starts.
Electronics & PCB Mounts — 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 |
| M6 Washer | 18 × 18 × 3 mm | £0.27 – £0.34 | £0.28 – £0.36 | £0.32 – £0.41 |
| Hex Nut M10 | 20 × 17 × 10 mm | £0.65 – £0.83 | £0.69 – £0.88 | £0.77 – £0.98 |
| 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.

Electronics & PCB Mounts — FAQ
Can you print a part for a mains enclosure?+
Not one that does an electrical job. Mechanical furniture inside an enclosure that is itself properly rated is fine — a bracket, a tray, a spacer. Isolation barriers, live-part covers, anything relied on to keep mains away from a person: no. Filament has no electrical rating and prints are porous between layers.
Will a printed case shield my circuit from interference?+
No. Plastic is transparent to EMI in both directions, and a printed enclosure does nothing for shielding. If you have an EMC problem or a test to pass, you want a metal or metallised enclosure. We can print you the internal furniture that goes in it.
Is it flame retardant?+
No. Standard PLA, PETG, ABS and ASA are not flame-retardant rated, and we will not imply they are. If your product has to meet a flammability standard, the part needs a material with a real rating and a data sheet behind it — talk to us about that before designing around a printed part.
Should you print the threads, or use inserts?+
Inserts, nearly always. A printed M2.5 or M3 thread, or a self-tapping boss, will take a few assembly cycles and then strip. Heat-set brass inserts cost pennies, take seconds to fit, and turn a disposable part into one that survives repeated servicing. We will design for them unless you tell us it is a one-time build.
How much does electronics & pcb mounts 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.

Plastic will not print in mid-air. Here is the 45° rule, what bridging really does, why supports leave scars, and how to design so you need fewer of them.
