Hillside 46 Case with Magnetically-mounted Tenting Solution

Huge thanks to @rmwphd for sharing the original files with me!  If you are interested in building this variant of the Hillside keyboard family, check out mmccoyd's repository here: https://github.com/mmccoyd/hillside/tree/main/hillside46

I absolutely loved the original case design, and I probably could not have created my own from scratch with my limited CAD skills even if I had wanted to.  The only thing I found even a little disappointing about the original is that the tenting solution it was designed to support seems to be perpetually out of stock (and expensive even if it was in stock).  I decided to come up with a 3D printed tenting solution so I can iterate and change the angle quickly whenever I want, while providing an option that is cheap, secure, and portable.

To hold the tenting solution in place, I designed 5x 8.2mm pockets on the bottom of the case as well as the top of the tenting object.  This might be overkill, so feel free to only populate as many magnets as you feel necessary and let me know if you find a lower number of them is sufficient.  I made sure to set the poles of the magnets to be opposite on each half of the case and tenting object so the two tenting objects as well as the two case halves will magnetically stick together for increased portability.

I also added a countersunk hole on the bottom of the case to make pressing a M2 heat-set threaded insert easier, as I found the original design resulted in lots of plastic blocking the screw hole after installation.  The countersunk hole has the additional benefit of making it easier (at least for me) to keep the insert straight while pressing it in with my soldering iron.

I opted not to include the lid here as I did not make any changes to it.  Check out the original model to download the lid here: https://www.printables.com/model/364122-hillside-46-keyboard-case-with-cover

Please post your makes and provide feedback.  Want a different tenting angle, different number/location of magnets, something else?  Let me know, and I'll be happy to make adjustments and upload variants as time allows!

Supplies I used:

• 20x 8.2mm magnets: https://www.amazon.com/gp/product/B08C4SQSM3/
• 10x M2 heat-set threaded inserts: https://www.amazon.com/gp/product/B0B8GN63S2/
• White PLA filament (tent): https://www.amazon.com/gp/product/B08QMJB48V/
• Clear PLA filament (case): https://www.amazon.com/gp/product/B0C2Q99H12/
• PLA-CF (lid): https://www.microcenter.com/product/632387/inland-175mm-pla-pro-3d-printer-filament-10-kg-(22-lbs)-spool-carbon-fiber
• Super glue: https://www.amazon.com/gp/product/B0006HUJCQ/

Print settings:

• Case:
  • Filament: clear PLA (to better see the LED under-glow)
  • Infill density: 15% 
  • Infill pattern: cross hatch
  • Other settings: adaptive layer height
  • Mirror along the X-axis to create the right side
• Tent:
  • Filament: white PLA (may better reflect the LED under-glow?)
  • Infill density: 30% 
  • Infill pattern: gyroid
  • Other settings: adaptive layer height
  • Mirror along the X-axis to create the right side
• Lid:
  • Filament: PLA-CF
  • Infill density: 100% (probably overkill)
  • Infill pattern: N/A
  • Other settings: adaptive layer height
  • Mirror along the X-axis to create the right side

Note: I kept tolerances on the magnet holes a bit loose to make it easier for printers with different abilities to print my objects.  I personally used a well-calibrated Bambu Lab P1S to print all the objects in my pictures, which resulted in many of the magnet holes (especially on the underside of the case) being a bit too big to hold them with a simple press fit.  I put a dab of Loctite 1364076 Super Glue in each magnet pocket to ensure everything stays in place.
