Reddit reviews UHU Tac Removable and Reusable Glue Pads for Fast & Cleanmounting, Non-Toxic, Ideal for Paper and Small Objects, 80 Tac Pads (99683),White

Three possible "avenues of inquiry to explore", to quote Inspector Lewis:

1. Apply electrical tape over the vents just below the termination of the headbands. You can "tune" the bass depending on how many louvers you close out. The one caveat is that the tape needs to be stiff but not resonate.
   
   
2. Mass load the baffles a little more stably than the typical mods with something with more mass than play-doh. I've read a few posts about how tungsten putty works the best, but that's getting into unobtanium territory. I like [UHUtac] (http://www.amazon.com/Saunders-Removable-Adhesive-Putty-99683/dp/B0000AQODM) a lot. The trick is once the baffles are loaded, you can "shape" the reflections by using something like a phillips-type screwdriver to impress "x" marks on the baffles strategically. It's a lot of fun to figure out and do because you can get a bunch of subtle effects this way. Combining this with an appropriate amount of cotton wool in the cups to tame the treble/ upper mids a little also relatively brings out the bass a little. make sure you take the time to weigh and use the same amount of cotton wool in both cups!
   
   Another option is to reshape the baffles but that's at the next level of modding.

Preferably you need the cap to seat the thumb covers properly.

but you could use some thing like Uhu Tac to apply it to the controller and keep it there until you do find a thumbstick replacement.

Instead of double sided tape, use sticky tac, more pliable and doesnt leave any residue.

looks cool

Have you thought about using removable glue pads like these to maybe add more support for the fans and absorb some of the vibration to reduce noise?

It's basically like slightly sticky Play-Doh, won't do much good on its own but I imagine that it would work pretty well if combined with those zip-ties.

Just be careful with tape, sometimes even that can damage the walls. Personally I'd recommend the tacky puddy to attach to the wall.

I'm already using this and it works well:

My question is how to stack them? I was thinking of getting some silver or black legos and making my own rack or something similar.

UHU Tac https://www.amazon.com/removable-reusable-objects-surfaces-99683/dp/B0000AQODM aka poster tac, will stick reasonably light stuff to textured walls and let them come off again pretty well.

you might know it as the white stuff that comes with glow in the dark stars.

I'm thinking something like this, like two of these. Super cheap as well.

I'm using this here

It's completely removable.

It looks like you might not be in the US, so you might not be able to order this, but something like this might work.

It's cheap, and one package should last you quite some time. Just rip off very small bits to stick your board to your battlemat. That should keep it from slipping around.

A bit of adhesive putty might have removed it, although precision tweezers might have worked better.

Have you ever tried these things to "glue" something on the ceiling? Works fine for me for the pulleys.

I don't think a system like the virtuix boom will ever have as less tension as a ceiling setup, since it has only one pulley (I have 5 double pulleys on the ceiling, which might be a bit overdone, but i would recommend at least 3 double pulleys).
