this is basically how the tissue master works; they are rebadged dremels if I remember correctly. I would think that you would need to CNC or forge such an attachment though. I would constantly fear that shape ways stuff (even the metal prints) would break from vibration.

As someone with a lab background I will throw this in: do not buy a used homogenizer or lab equipment in general from eBay or anywhere, especially for anything you'll ingest/vape. God only knows what horrors have passed through that machine. Even with detailed records of what it was used with (good fucking luck getting those) it's unlikely you'll be able to clean it to any reasonable approximation of safe. Some things you can create a reasonable amount of safety (e.g. a used scale you dismantle and clean heavily with appropriate cleansers that won't ever be in direct contact with whatever you ingest) but even then there's a certain amount of risk. It may seem like overkill but I would hate for someone on here to get injured or even die because they got a used micropipetter, homogenizer, etc that was used with a nasty solvent or some relatively unknown chemical that was tested at whatever pharma company closed down and cleared house.

That being said I have some access to lab equipment used in food industry, some in my house, and a decent amount of chem lab experience. I have an entirely different career now but I still love to utilize this stuff for novel approaches (i do it in food a lot). I'm new to DIY juice but I just got my first shipment in; I'm playing around and once I hit something I like I'll see if I can get it on their ultrasonic homogenizer. They might be wary of anything that could potentially contain nicotine though, even if I do 0% I don't know if they'll trust me. At home I have some equipment that is mostly of little use to e-juice creation but I have some ideas for novel applications.

This has me thinking though. I love rotostators because there are a ton of culinary applications; I'll put my mind to seeing if I can think of any DIY solutions because I would love to have one but fuck spending 800 bucks on a rebranded dremel with a hundred dollar tip

This got me thinking... a coat hanger is slightly too small to fit in my dremel as it is only 2mm and the dremel attachment shafts are 3mm in diameter.

Just took an old dremel point grinder attachment and bent the tip... worked amazingly well. WOW, never seen VG blend like that hahaha!

It needs to be longer though and just found these...

Those are perfect! Bend the end based on how aggressive you want it to be and on the end of a dremel it will blend the shit out of anything!!! I just ordered them and they should be here tomorrow. Will test and report back.
