I design this here with the goal of storing parts I needed an organizer so here

it is its holds 3 hots ends, extruding unit and then small parts like grease, screws, socks or whipers

the pictures is what im storing in it and there is much room to move things between them,

in the pictures you may see there is a red part, that failed due to warping but it shows it can hold a hot end with fan

i printed in PLA generic no issues with two prints on a 0.4mm

nothing special as i rarely design parts but it works well
