Knight’s Grooming Chest for Philips OneBlade (QP4631/65) (Case) – Kingdom Come Edition

Knight’s Grooming Chest– Kingdom Come Inspired
For Philips OneBlade 360 QP4631/65

Introduction

Even a knight needs to look presentable.

This is the Knight's Grooming Chest. A Kingdom Come: Deliverance II inspired travel case built specifically for the Philips OneBlade 360 QP4631/65, including the Kingdom Come II Limited Edition. It will not fit other OneBlade variants.

Designed from scratch on the proven mechanics of its predecessors of the compact case series. Inside, the case holds the OneBlade handle, two blades in dedicated slots, two compartments for extra attachments, and a precision cable holder refined over multiple iterations. The two air vents on the lid let moisture escape after use, integrated into the metal bar detail on the exterior so they disappear into the design.

At around 90 grams of filament, it's one of the most efficient cases in its category. Fully print-in-place. No supports. No assembly. Works straight off the bed.

The cover photo shows the case hand-painted in a medieval wood and iron style; more on that below.

Compatibility

Designed exclusively for the Philips OneBlade 360 QP4631/65.

⚠ Not compatible with other OneBlade models. The QP25xx, QP26xx, QP27xx, QP28xx, and OneBlade Pro series all have different dimensions and will not fit. Check the model number on your device before printing.

This design does not modify or attach to the device itself.

Printing Specifications

Let the print cool fully before removing from the bed for best hinge and spring release.

Hand-Painted Finish

The cover photo shows the case painted in a medieval wood and iron style using hobby acrylics. Want to do the same? Here is how.

Print in (matte) black PLA. The dark base acts as a natural shadow in all the recesses and means any thin spot in your paint just looks like depth. Start with a dark brown base coat, then sponge on a lighter brown in irregular patches for wood grain texture. Keep it uneven on purpose. Dry brush beige over the raised surfaces to bring out the engraving edges, then dry brush silver on the metal bars and rivets,

Finish with a black-brown wash: one part matte black acrylic, five to eight parts water, and a small drop of dish soap. Flood it over a section, wait twenty to thirty seconds, then wipe the raised surfaces clean. The wash settles into the engraving lines, the lettering, and every edge. That step alone takes the model from painted to aged.

If you have an airbrush, use it for the base coat and edge shading before switching to brushwork for the rest. The deep engravings do most of the work; the paint just reveals what is already there.

Spring-Loaded Lock

The latch is the mechanical heart of this case. The button is shield-shaped, with the Kingdom Come: Deliverance logo engraved into it and the Roman numeral II on the lid directly above.

The spring prints as one piece and requires no assembly. It sits in tiny grooves that prevent it from shifting up and down while still allowing clean, consistent compression. Crucially, the spring only compresses during the closing motion. When locked or fully open it rests in a relaxed state, so the filament won't deform over time. Press the button and the lid pops up about 2mm, just enough to grab it easily. Close it and it snaps into place. How satisfying that snap feels depends on your filament choice.

Development

Multiple prototypes were made to refine the spring geometry, latch, button tolerances and able holder compartment. The aesthetics went through just as many iterations alongside the mechanics; the engraving patterns, gothic lettering, and surface details were all reworked across versions to get closer to the medieval look of Kingdom Come: Deliverance II.

I originally tried Blender to sculpt the ornamental details, but without enough experience in that workflow I ended up doing everything in CAD. It took more effort to get the organic shapes right that way, but the result is cleaner and more printable for it.
