Lily58 Case and Palm Rest System

Lily58 Wireless Ergo Keyboard Case System

I designed this case because I was not satisfied with the available
options.

I wanted a case system that I could easily use in two main
configurations:

• As a smaller, portable form factor for when I travel
• A more stable and robust platform for when I’m at my desk that includes a palm rest (I know we’re supposed to have our hands floating, but you know...sometimes…)

With the ability to tent it if I want to, and also to hold a larger
battery than the standard 150mah one that is recommended by most builds.

The look might not be to everyone’s liking, but I prefer simple shapes
that look functional (like the Dygma Defy).

The design has

1. Large cut out on the main case for a 1500mAh 524261 LiPo
   battery

2. Four specific cutouts on the main case to apply the 3M SJ5302
   non-slip bumpons,
   there are counter cutouts on the base to allow the two to bind
   together flush and not be raised by the bumpons

3. Four locations for 8x3mm Neodymium
   Magnets
   on the case, and on base to keep them aligned and temporary fixed

   1. When applying the magnets, I suggest you do it to one of the cases first, then on the other side use the reverse polarity so they tend to stick together when carry them around
   2. Then you can figure out which orientation of magnets you need for their respective bases

4. On the base, there is a cutout for the Kensington Palm
   Rest that is a snug
   fit so they won’t fall out easily, but are also not permanently
   affixed

5. A MagSafe slot on both the case and the base for the adhesive
   MagSafe
   Rings
   that are used for tenting

   1. If you want to use the same tenting system I use, you will need two of these MagSafe Magnetic Tripod Mounts and two of these Manfrotto MP3-BK Mini Tripods
   2. When tenting, I direct the two legs to face to the inside edges, and the third leg is not used, the outer edge of the case becomes the third back leg of tripod
   3. You can then tweak and adjust until it is stable and at the angle you like
   4. The tenting also works with the large palm rest base, although you can’t really put pressure on the inside corner of the platform otherwise it tilts ## Parts List

For the cases (left and right):

• 2 x 1500mAh 524261 LiPo battery
• 8 x 8x3mm Neodymium Magnets
• 2 x MagSafe Rings
• 8 x 3M SJ5302 non-slip bumpons
• 10 x M2 bolts (length depends on your standoffs that you use)
• 10 x M2 standoffs (length depends on whether you are using a plate or not)

For the bases (left and right)

• 8 x 8x3mm Neodymium Magnets
• 2 x MagSafe Rings
• 8 x 3M SJ5302 non-slip bumpons
• 2 x Kensington Palm Rest

I printed these using FDM on a BambuLabs P1S using OrcaSlicer

Mirror the provided files to get the Left Side version

Settings for both the case and the base were

• 0.4mm Nozzle
• 0.20mm Layer Height
• Esun PLA+ Matte Black Filament
• 15% Infill, 3D Honeycomb (anything will be fine)
• I used top surface ironing, although if you’re using a Matte PLA it can make the color shift towards a whitish tone which might be undesirable.

For the main keyboard case, you should add a pause at layer 17 to be
able to insert the magnets. They may be snug but it shouldn’t affect the
print, to keep the case as Low Profile as I could, I couldn’t have more
than 2 layers below and 1 layer above the magnet, so the top layer may
not close completely, but given that it is under the keyboard, that
shouldn’t be an issue

For the desktop base, you need to have a pause at

• Layer 6 to embed the MagSafe ring
• Layer 19 to embed the magnets, this is much easier than with the case because there was plenty of leeway in the design to make these more comfortable

When applying the magnets, you should drop some super glue into the hole
so that the magnet won’t stick to the hot-end when it es over
