Removed a little plastic from where the inner of the SD-card opening butts up against tachyon's PCB, the separators between the USB/ethernet ports and enlarged around where the hdmi connectors should be. (Tools used: craft knife, small file and 4mm drill bit)
Still need to add something to the inside of the clear plastic button/LED bezel to get it to reach tachyon's button though
Oh, and added 2 x elastic bands 
Looking good Zedstarr!
If you are interested in our 3D cases, check our the earlier versions here:
Happy to send you one for feedback!
Thanks
Nick
Happy to receive one for feedback - I just used the Pi case as I had a spare one lying around 
Because the Tachyon needs a bespoke case, I designed one that you can find here on printable if you are interested. It supports a battery holder on the side, the audio adapter board, and an optional PCIe extension board.
I haven’t yet tried all the combination of the case that I uploaded, so please let me know if something does not work as expected.
Hey mkende! Awesome!!
Would you be ok if we added this to the list of 3d print cases (with attribution of course!) here? If so, can you shoot me an email at nick@particle.io - we have a contribution agreement that protects your idea and make sure I've circulated it.
I will give one of these a print tonight and let you know - I really want a battery holder in my case
Thanks
Nick.
Sure of course you can list them on your website, I’ll send you an email.
I updated the files as previously I didn’t account for the fact that the Pimoroni NVMe board is longer than the Tachyon 
. Now I think that I have tested all the variation and that everything works correctly.
@mrlambchop Re: Tachyon 3D printed case
I printed the Tachyon case. It looks and fits great!
Just needs a height adjustment if one is using a Pimoroni NVME case.
Any chance you could request Arty Li to adjust the height to accomodate the Pimoroni NVME board with the Tachyon? Thanks.
Looks great!
I’ll ask Arty to come by with a tweak to his case
Since this case, we built one with a battery stand and a much nicer button - I’ll share a quick video of my device tomorrow
@mrlambchop, will you be sharing the STL for this new version soon 
Hopefully, very soon, dev will fix the issue regarding the need for a battery to boot up a Tacyon
Regardless, a couple of variations of the existing Tachyon case would be nice.
Hi @peekay123 @zpm1066,
A new Tachyon case (v2) update is available for your reference to improve the power button.
Tachyon plus single cell battery and/or 3 cell battery pack
dev will fix the issue regarding the need for a battery to boot up a Tacyon
Without a battery, the Tachyon can be powered on using a DCP (Dedicated Charging Port) charger.
Hi @Arty Thank you for implementing the several case variants. It’s much appreciated. The revised button looks pretty cool! The top height adjustment should be fine to accommodate something like a Pimoroni NVME base.
With the original case (see photo above), I have the single battery adjacent to the 40 pin header so that the main case compartment remains empty and the case is wider. In the redesigned case, how will the battery placement be handled within the case?
To keep the main case compartment area free for HATs, as in the original case, the base height could be adjusted to accommodate either a single-cell or the heavier 3-cell battery with some way to make sure that the battery is secured to avoid movement.
Thoughts? Thank you.
Hi @zpm1066 , thank you for the great ideas.
If the single battery is placed next to the 40-pin header, it will make the case wider, which is not as elegant as the current design.
Let me find a balance between functionality and elegant design.
By the way, you can route the battery cable through the slot.
+1 for the 3 cell battery variant!
Hi @Arty ,
Yes, a side battery holder would be functional but an elegant solution.
The preferred option would be to have the battery in the base or have a battery case the same footprint as the main case and have it clicked in to the main case, so it can be attached if needed. I do that with the Adafruit Feather cases.
Update:
Tachyon extension case compatible with the Pimoroni NVMe BASE.
to to adjust the height to accomodate the Pimoroni NVME board with the Tachyon?
Thank you for your feedback.
Hi @Arty , the case with accommodation for a Pimoroni base looks fantastic! Thank you again for the update.
It looks like you have several variations of the case top, as Nick showed one where the top had space for a SSD1306 OLED.
Regarding support for a battery (single and/or 3 cells), What did you decide on? for example, accommodating a battery in the base or having an additional battery attachment of some sort?
Thank you.
You're welcome. Could you please print out this version to verify it works on your side? And let me know.
It looks like you have several variations of the case top, as Nick showed one where the top had space for a SSD1306 OLED.
Yes, it was made before with no battery inside, and the last line on the OLED is a dynamic string that horizontally scrolls through some useful information. It looks really cool and interesting, and it has low power consumption. I’ll buy more OLED peripherals to ensure the design is generally compatible.
Regarding support for a battery (single and/or 3 cells), What did you decide on? for example, accommodating a battery in the base or having an additional battery attachment of some sort?
In fact, I have tried designing a single battery inside the base, but it makes the case unit look too thick. I also have an optional stand design with an integrated battery, but it is not elegant either. To maintain the concept of simplicity and elegance, I still haven’t found a good way to balance this elegant design so far.
Thank you.
