precautions
- Please read the “FAQ” for questions or problems after or during assembly.
- As for the acrylic plate included in the package, please remove it carefully as it may be scratched when you remove the protective seal. Wetting it with water, etc. will also make it easier to peel off. Returns and refunds will not be accepted due to scratches.
- Due to the nature of acrylic plates, scratches and cracks may occur rarely during processing and transportation. Due to the nature of the product, it is assumed that these points were agreed upon at the time of purchase, and returns and refunds will not be accepted due to scratches in the same manner as above.
- Specifications and prices are subject to change without prior notice. Please read the terms and conditions on the sales page for details.
How to assemble Gravity45 (acrylic kit)
The assembly method will be explained from here.
What you need for assembly
- Precision Phillips screwdriver
- Precision Tweezers
Things that would be useful
Recommended maintenance products
- Anti-static spray (Acrysunday Polycare F70)
- Kyung Cham cloth or other fingerprint wiping cloth (e.g., eyeglass wipe)
This build guide is illustrated using a prototype.
Some screws are different from those included in the package, but priority will be given to those included in the package for the complete set of parts.
Please understand that we are not responsible for any loss or damage to your property.
First, remove the acrylic protective film.
Although very tightly glued, peel off the edges of the acrylic release paper with your fingernail and then slowly peel it off.
If it is difficult to peel off, one method is to place it in lukewarm water.

Install the rubber feet referring to the illustration.

Install the top acrylic so that the short edge of the top acrylic is on the left side, insert screws from the top and apply spacers from the bottom to screw it in place.

Place the top acrylic on the board and fit the key switch.
For HiPro kits, only Cherry MX compatible keyswitches are available.
For LowPro kits, Kailh choc v1/v2/Gateron LP3.0 key switches are available.

Fit the keycap.
Note that the keycap position is different for 30% layout/40% layout.

Attach screws and spacers for the Artisan acrylic plate to the top acrylic.
As shown in the figure, insert the screws from the bottom side and install the spacer on the top side.

Place the artisan acrylic plate on top of the spacer and screw it on top.
The center keyswitch is “Cherry MX compatible only”. There is no mechanism to fix them with an acrylic plate, which is a specification.
Attach your favorite artisan keycap of your choice.


Finally, screw the bottom acrylic in place and you are done.
