Pen sander.

looks like a nice tool, i assume it vibrates, that would be more controllable in tight places.

i have an old oral b electric tooth brush i converted to a mini sander but its sort of an orbital rather than vibrates.

these small sanders do come in very handy.

It reciprocates in the out but very fast.
 
I've been using the 3-speed, DSPIAE ("Illusive Shadows") reciprocating sander for about a year and it's ideal for tight spots that otherwise might be very time-consuming to access. For 3D resin printing it works great for removing layer lines when the broad square head is attached with the 3M 180 grit adhesive-backed sandpaper it used. The rounded head works well to smooth out tight corners too.

The unit charges in <30 minutes and lasts up to 45 minutes. It includes a pressure-activated stall feature if it's pressed too hard against the surface. I've used it on hardwood bases to smooth out routing imperfections as well.

Full Disclosure: My first unit died after a month, but had worked so well, I immediately bought another, which has worked fine.

Bought one-off Fleabay that has a transformer for plug in power. Works great so far, but I don’t use it a lot, so…

The product I mentioned is cordless and uses a USB cable to rapidly charge.
I use mine constantly, so it's perfect for my needs. Your milage may vary.
 
What I’d like to see is someone manufacture a right hand drill for a manual pin vice hand drill. Dremel sell a right hand drill, but it’s way to large to get into really tight spaces.
 
The sander sleepy fish bought is a P.O.S. - no power, very brittle attachment (s).
The Dspia is an in line sander that is superior for tight spaces - must let the abrasive chosen do the work!
The 12v DC plug in types (Proxxon) are wonderful also, they sand side to side and are able to be used more aggressively.
All the tools have their place and all are useful!
I have all three types.
Just my viewpoint.

Someone did, long, long ago. They're called "dental engines." They have handpieces in many configurations, straight, 90 degree angled, 45 degree angled, etc. and drills and burrs of all sorts. They run with a right-hand twist or a left-hand twist, depending on which direction you select by throwing a switch. Speed is controlled with a foot pedal. Tremendous torque compared to these low powered DC tools or even to a Dremel MotoTool. Built to the highest standards and should last a lot longer than you will. Can be had used on eBay, etc. in good shape for under a hundred bucks. New, with a handpiece, they'll run you close to a grand. Their being replaced by modern high-speed low-torque air turbine handpieces which are a big improvement for their intended use, but not suitable for high-torque-dependent modeling, so there are lots of the old belt driven models on the used market.

There are several top brands. Buffalo Dental Equipment is but one of the top three or so.

On a similar vein, I saw and have purchased the following micro drill ideal for tight spots and repetitive drilling for tree nails etc.

In a similar vein, I have used this "nail drill" extensively for sanding, drilling in soft wood and carving. It certainly does not have the torque that a Dremel has but is great for minor jobs. You can get them powered by a USB "brick" or rechargeable. The real advantage is its small size. it fits easily into your hand and is not bulky like a Dremel. For a guy like me who is naturally clumsy it is a big advantage. It does not take Dremel size shafts. It take 3/32" shafts. That being said I have found arrowmax drill bits on Amazon and carving burrs on model expo that work great.

Another advantage is price. I bought mine on Amazon for $12. It is now on my bench at all time with my Dremel put away until I need to use it to cut tubing etc.
