Layer lines gone in 30 seconds.
The cordless detail sander that gets into the corners sandpaper can't reach, without wrecking the print.
- Gets into crevices, panel lines and inside corners
- Three speeds, smooths without flattening detail
- Overload chip cuts power before the motor burns out
- 8 head shapes, storage case and full sandpaper set included
Same print. One pass.
Layer lines are the tax you pay for printing at home. Sandpaper flattens the detail you printed the model for. This doesn't.
Built for the fiddly bits.
Reaches what fingers can't
Crevices, panel lines, inside corners and undercuts. The places a sanding stick simply will not go.
Three speeds, 2,800 to 3,600 SPM
Lift layer lines without flattening the rivets and panel detail beside them. The LED strip shows which speed you are on at a glance.
Under 0.1mm of wobble
Horizontal deviation and side-to-side play are both held under a tenth of a millimetre. Wobble is why cheap sanders chew detail instead of lifting layer lines.
54 grams, genuinely pen-sized
178mm long and lighter than a marker. No cord dragging your hand off the piece, and no fatigue an hour into a session.
Overload protection built in
A smart chip cuts power before the motor takes the damage. Cheap detail sanders burn out in weeks precisely because they have nothing like this.
Eight head shapes in the case
Slim, rectangular, square, triangular, curved-face, right-angle, round and sled. One of them fits the awkward bit you are looking at.
Every claim is on the spec sheet.
Most detail sanders die in two weeks.
Look up any of the cheap ones and you'll read the same two complaints on repeat: the motor gives out after a fortnight, or the sanding head pops off halfway through a pass and you're re-sticking sandpaper instead of finishing your build. We built around both, then backed it with a twelve month warranty. If you have already thrown one of these in a drawer, that is who this is for.

Three steps, no learning curve.
Clip in a head
Coarse for shaping, fine for finishing. Swaps in about two seconds.
Pick your speed
Low for delicate detail work, high when you need to move material.
Let it do the work
No pressure needed. The reciprocating action follows the surface instead of flattening it.
What builders say.
Makes sanding small parts so much easier. I build Gundam kits and this saves me a ridiculous amount of time compared to sanding everything by hand.
Really impressed with how precise it is. Easy to get into tight areas without accidentally taking off too much material.
The build quality surprised me. It has a nice weight to it and feels much more premium than I expected.
Perfect for cleaning up seam lines and rough edges on model kits. Been using it constantly since it arrived.
If you do a lot of miniature or model work, this is one of those tools you don't realise you need until you have one.
Very smooth and controlled. Doesn't feel overly aggressive like a rotary tool, which makes it much better for delicate pieces.
Cut my sanding time in half. Especially useful for repetitive work where hand sanding gets annoying.
The small size is probably my favourite part. You can actually reach areas that would be awkward with a normal sander.
I was worried it would be too powerful for plastic models but it's actually really easy to control.
Feels solid in the hand and the vibration isn't uncomfortable. Used it for a few long sessions with no issues.
Great for sanding 3D prints. Makes cleaning up layer lines and small imperfections much faster.
Bought it mainly for scale models but I've already found a bunch of other little DIY jobs to use it for.
Way more convenient than constantly folding tiny pieces of sandpaper to get into corners.
Very accurate movement and surprisingly quiet. Definitely improved the finish on my builds.
One of the best additions to my modelling setup this year. Simple tool, but it makes tedious sanding so much easier.
Before you order.
Will it damage fine detail?
On the lowest speed it lifts layer lines without touching panel lines, rivets or engraved detail. Most people stay on low for miniatures and only step up for bulk material removal.
Does it work on resin and FDM?
Both, plus styrene, wood, putty and filler. The grit range in the box covers coarse shaping through to a satin finish.
How long does the battery last?
About 100 minutes of continuous use, and it charges in roughly 20 minutes over USB-C. In practice that is several build sessions between charges.
What is actually in the box?
The sander, eight interchangeable head shapes, a charging cable, a storage case, and a full sandpaper set spanning grits 400 to 1500 in both durable and standard backing. It is a complete kit, not a bare tool.
How fast does it ship?
Most orders arrive in 7 to 14 days. Shipping is free on US orders over $75, and every order gets a tracking number the moment it leaves the warehouse. That window is our current supplier line and we would rather quote it long and beat it than the other way round.
What is it not for?
It is a precision tool for small parts. Miniatures, models, prints, small resin and styrene work. It is deliberately low powered so it does not destroy detail, which also means it is the wrong tool for stripping furniture or large flat panels. Not suitable for under 14s.
What happens if it breaks?
Twelve month warranty. If it fails in normal use inside a year we replace it, and you do not ship the old one back. We put that in writing because the failure rate on cheap detail sanders is the entire reason this product exists.
What if it isn't for me?
Thirty days. Send it back for a full refund, no restocking fee and no interrogation about why.
Thirty days. No hard feelings.
Run it on your worst print. If it doesn't do what this page says, email help@finelayer.store and we'll refund you in full, with no restocking fee, and we won't make you argue for it.
