Thinsulate is an excellent case foam alternative. It is an effective lightweight acoustic dampener that is extremely versatile due to its wide compression range, making it usable for virtually all keyboards.
Dimensions : 500mm x 120mm
Thickness when fully compressed: 1mm
Thickness when uncompressed: approximately 13mm
You will need to trim Thinsulate to your case internal dimensions.
You will need to compress the Thinsulate as you are assembling your board together.
Thinsulate may fray. Use with care! Not recommended as plate-PCB foam.
These new films are now die-cut and ordered through a manufacturer rather than being home-made in my (DrewKeys) garage. Dimensions are tighter, more accurate, and generally look more aesthetically pleasing. Compression ratios are better, as the material is softer than before. They now ship in easy to peel sheets rather than all in a single bag. (Check the video link!) https://www.youtube.com/watch?v=fSjxzWGLDBs
Fits all switches meant for thicker films! (Cherry, Gateron, JWK's, etc. all good)
One of the (if not the most) thickest switch film that still perfectly fits the majority of switches due to the compression of the rubber silicone material. Comes in 4x5 sheets packaged in resealable bag.
Installation: I findputting the switch films on the top housing makes it easier to applythan to put it traditionally on the bottom housing. There should be two tiny bumps on the top housing on the side where the leaf would be.Make sure the films are between the two bumps and the top housing legs!Once you've put the films in this way, they should be perfectly be aligned.
These o-rings (oring) fit around your 60% PCB and plate assembly to help isolate the assembly from the case and create a bouncier / softer typing feel. They are compatible with a wide range of tray mount and gasket mounted cases.
FOR EXPERIENCED USERS ONLY.
You will need clip in stabilizers for your backspace and spacebar. They can be purchased here (link). Clip ins allow the gasket to fit tight cases because they have more clearance.
You will need to remove the tray mount stand offs of your case. This may require a Dremel! The stand offs create hard points and prevent this modification from working as gasket mount.
You will need to file your PCB to allow the gasket o-ring to be seated properly on the inner case tabs. Take caution when doing this!
If your case does not have inner tabs, you may need to purchase bump ons.
You may need to solder your assembly together for maximum strength.
....and many more
If you choose to use a hotswap assembly, be sure to remove the assembly from the case and remove the o ring prior to removing the switches. Be careful- switches will fly out with a hot swap assembly!
For best results with a hot swap assembly, your assembly will need stand offs / spacers installed between the PCB and the plate for better structural support.
If you choose not to file your PCB or Dremel your case, this modification can still improve the sound of your board, but very slightly.
Using screw in stabilizers may prevent your assembly from fitting into the case. They may also lead to the o ring breaking if you try to force it in!
