I do have one recommendation for anyone that takes on the MK735 project...and that is to consider using a textured build surface for some of the front exposed surfaces.  As seen in the above photo and the DSC00111.jpg attachment posted on 6/22, we printed the front facing objects on a Prusa textured powder coated PCI plate (both "Front Panels", "Door Frame Upper", "Door Frame Lower", "Front Insert" (switch panel), "Door Grill Dovetail" and "Lockset Bezel".  We love the results.  It hides all those minor little build surface lines, helps hide the join between the upper and lower door frames and throws a bit of sparkle in there to boot.  It really helped achieve one of the original MK735 objectives; "It should not be obvious that it was 3D printed".

Anyone have a cost estimate on this bad boy?

@charles-h13, the 3Dwebe website has a list and links to most items that we used, but there is not a true bill of material there yet... Thanks for asking the question, we'll get something better put together that spells out the items and the expected total. 

Cost wise to get the MK735 to the same state as a typical DIY "off the shelf" chassis, you're looking at a little over $200 US.

That price includes:

  • The MK735 stl files and documentation
  • 3kg of good quality APLA+, HTPLA+ or PLA
  • 1kg of TPU (only about 250g is needed)
  • 3 x 92mm fans (or 80mm fans)
  • Power switch (we used one with a power-on led built in)
  • M3x12mm self-tapping screws
  • Disk drive mounting screws (#6-32 x 1/4")
  • Optional: USB 3 or USB 2 front panel connector
  • Optional: Lockset (printed latch can be used instead)
  • Optional: Magnets for magnetic door latch

You will of course need to add to that whatever computer gear you prefer, such as:

  • Motherboard, CPU, memory
  • Power supply
  • Disk drives/SSD
  • SATA cables
  • etc...

No special tools are needed.  If you have a 3D printer, you'll most likely already have what you need.

@toby-k, I'm not familiar with the website which is hosting the files, what happens if you update the model files? Will we be able to get the updated files for free?

Yes, that is my intent...but I'm double checking to make sure.  I have added a .jpg file to the MK735 download package and that file is now listed in the package of a previous purchaser.  However, when the package is re-downloaded, that new file is not included.  I believe that is because the new file has not yet been checked and approved by MyMiniFactory (it still has a pending status).  They go out of their way checking what we post and the approval process can take days.  I'll confirm here when I see that new file appear in the package download.

Wow. Initially I thought this was cool, but seeing the details in the blog... Wow

Awesome job and now I'm realizing that my 7 bay Thecus is 10 or 11 years old now 😯 (5 or for 7 WD green drives are still original too!)

I have looked at replacing it a few times, but it sits partially between floor joists which drastically limit my replacement options. Can't wait to see the final details (e.g. outer dimensions) and how you''ll distribute/license it (e.g. if it doesn't fit the space, can I modify it myself). I have a feeling that the way the door opens will make it not work for me as is 🙁

One thing that would be really nice is built in support for installing filters to help control dust. Any time I've looked at non-datacenter storage solutions I've always been surprised they don't think of that.

Really nice work though.

@gnat, good news...  An available add-on filter kit has cleared prototyping and is currently running through beta testing.  Full front door and power supply airflow filtering, all 3D printed except for the washable "off the shelf" filter material (about $2 in the USA, and you can make at least 2 sets of filters from that).  Hoping to release it in about two weeks.  Requires about 20 hours of printing and 200g of PLA if you are retrofitting an MK735...much less if you print the filter add-on instead of the standard door grill when printing your MK735.
