 i designed a modular organizer with a topographic map style here are the features 

MODULAR DESIGN you can print multiple units and stack them side by side to create a larger customizable setup

T-SHAPED INTERNAL TUNNEL inside the organizer is a t shaped tunnel that runs through the body allowing you to insert hooks and accessories anywhere you want 

HIDDEN STORAGE the top part (layer 5) opens up to reveal a hidden storage area its for small items like coins and wallets or anything  else you you want to keep out of sight also when you hide the coins and wallets it just looks better 

THE LAYERING I've chosen this style cuz it looks good the layering will give it the look i want XD

the 2 photos are not the final model i paused working on the organizer cuz the printers hotend heating assembly  broke :( making it impossible to continue in time for the contest ill resume once the replacement part arrives
