Ohuhu 320 color set marker case box holder shelf

Convert Your Marker Bag into a Usable Shelf! – Ohuhu Honolulu 320 Storage Inserts

These custom inserts are designed specifically for the Ohuhu Honolulu 320 marker case, maximising storage efficiency while improving usability.

Each insert holds 7 × 7 markers (49 total), and the full setup supports up to 294 markers (6 marker compartements). 

The layout is optimised for maximum capacity with minimal wasted space, making the most out of the original case.

The inserts feature a tight-fit design, keeping markers securely in place. This allows flexible use:

• Horizontal case position → markers stand upright
• Vertical case position → markers lie on their side

This effectively turns the case into a functional shelf, making it much easier to access and return markers during use.

⚠️ Due to the tight fit, corner marker slots may be slightly harder to insert/remove markers, but this ensures overall stability and compactness.

Because of the tight spacing, the inserts can be made shorter, reducing both print time and filament usage without sacrificing performance.

The design is minimalistic and visually unobtrusive, once filled, the inserts are almost invisible inside the case. 

It also does not interfere with closing the zipper, ensuring easy transport and everyday practicality.
