Fantastic idea. I had one of these for cleaning algae off of the rocks in my fish tanks that was sitting around doing nothing since i learned how to balance the tanks. Now it has a use again. Thank you.

Ingenious. Thank you so much for sharing! Gonna try and use this for my 3D prints. Bless you sir!

Excellent video, this will be very useful for getting into tight areas. The velcro attachment system looks great too. Thanks!

Bristles can turn into lumps of grass with some green paint 😁

Just found this, and it's a great idea. I had just recently done so with a regular Oral-B toothbrush I was replacing because the bristles were worn but the brush still operated fine. The bristles wouldn't pull out without damaging it so I just cut them down sanded the end flat used a piece of double stick tape and cut a piece of sandpaper to fit, stuck it on there, and as the French say voila. It seemed to do a subtler job but that's okay when doing fine sanding.

Fabulous idea! I'm currently building a motorcycle model, (HONDA CBR 1100XX), and I've had hard time smoothing the top seam on the gas tank where it's actually concave and smaller than a dime. I've used a much fancier one for cleaning rocks, but it has the annoying feature of pausing for a second to remind you to switch quarters of your mouth... As cheap as the Dremel discs may be, it would probably be even cheaper to buy larger sheets, (and easier to trim down as well.)

Just what I needed for driftwood projects. Love this! I can't wait for the end results. Awesome idea.

Ingenious!!!!!! Jet intakes don't seem so daunting now. Thank you for sharing!!!!!

Thanks! Have an old power toothbrush in the workshop - can see a couple of uses for a mini sander :)

Very clever! I’ve modified one to use in lock-picking sports (inspired by The Lockpicking Lawyer). But never considered as a parts sander!

This is perfect for me. I use paper clay in items I create and hand sanding, even though it might be a small area, can be tiresome. Love this idea.

Great for stubborn plaque too!!!!!!! 😁

This is a great idea. Im going to do this to sand personalized pens I make. Thanks.

I did it a couple of years ago with a double sided tape only. It works great.

Cool idea!

Soon as I seen this video went in my bathroom and got the one they don't use and conformed it into what you just did thank you so much

Great use for repurposing an old toothbrush. Thanks for sharing. I wonder if it wouild work out cheaper to use orbital sanding discs rather than the small ones.

Hey Rex - your channel is really informational and to the point. Thank you for making all these videos.. I am binge watching them. I've come back to this hobby again just like you.

Cool little tip

Brilliant ! I m am going to try it on my acrylic paints to erase buildup on canvases. Would u again explain the # sanding disc and the disc I should order. Appreciate ur video!

Ingenious !!!

Great dang idea

There's no end to human ingenuity! Brilliant (shame about the focus though :() Many thanks, I plan to make one of those this afternoon!

WILL TRY THIS!

got one that just vibrates but think i ll pick one that dose what the one you got

LMAO!!! The genius is in its simplicity. Friiggin brilliant.

Awesome! Doing this right away!!

Gonna do this in the morning 👌ty

Brilliant!!

You are Genius!

At cvs they have them for 10.79 and the second one is 40% off.

Genius, I was about to buy a microlux micro sander for $60 I have a bag full of these in my garage xD

Great concept.

Clever!

Great Idea. Thanks

Man I am really looking for a quicker way to remove nub marks and seams. I think I'm making a trip to wal-mart later

Gee! I got all that. I think I'll need a brand new Toothbrush Though

This could be good for removing layer lines on pla 3d Prints

I have a question if you don't have velcro could you just put a piece of tape and then the sandpaper

I did this about 10 years ago but found thst I didn't really use it that much.

have you tried using this to brush your teeth? probably good results.

Thanks man

A micro orbital sander 🤤

What kind of velcro did you buy?

Nice! I'm curious if there is any specific reason to chop down the sandpaper? Would the sandpaper fly off?

Love it

I wonder if you could turn it into a micro polisher tool

What a hummma see?

How many inch is your sanding dis? I am trying to find in amazon

i have a doubt, i have a dremel, but i feel it's so strong that ruins a lot of the tiny pieces. is this a better option ?

That one place is always sold out 😢😢

One is on its way from my otc humana store for free 😂😂😂😂

Very loud, is that just because of the cheap toothbrush? Also has anyone told you that you sound like Nathan Fillion?

Instead of trying to teach people something you should take the time first and learn camera skills
