# Modular Hexagon Shelf A quick and budget-friendly way to turn your smallest filament leftovers into a sleek, 3D-printed Modular Hexagon Shelf. ### v.1 [ [download](opensource/shelf_01/diy_project_depot_shelf_01.zip) ] ![segment assembly](opensource/shelf_01/assemble_01.webp) ![segment assembly](opensource/shelf_01/assemble_02.webp) The shelf is made of hexagonal segments and can be assembled in different configurations to suit your needs. The connectors can be glued for extra strength, or left unglued if you prefer flexibility — it all depends on your part tolerances, expected shelf loads, and whether you’d like to reshape or move the structure later. ## The construction consists of 4 elements 1. [Plastic tube](#Plastic-tube) 16mm cut into 230mm pieces 2. [Corner full](#Corner-full) for the base and shelf edges 3. [Corner side](#Corner-side) for the outer parts of the shelf 4. [Shelf segment](#Shelf-segment) *** # Plastic tube The tubes are made from standard round cable channels, available in hardware stores at around €1 per 2400mm stick. The shelf size was designed so the tube can be cut into equal parts with almost no waste. One stick is divided into 10 parts of 230mm, taking into account cuts and small errors. ![tube segment](opensource/shelf_01/tube.jpg) For easier cutting, there’s an optional helper part that lets you measure and cut the tube more precisely. This is not required but is useful if you don’t have proper tube-cutting tools. ![tube measure helper](opensource/shelf_01/tube_measure.jpg) ### Print - Printing time of the helper: ~45 minutes - Weight: ~23g *Tip: You can use tubes of different lengths, which will give you shelves of different dimensions. In that case, the connectors will need to be redesigned, as this version is optimized for 230mm tubes.* *** # Corner full This connector has 4 openings and can be used anywhere in the shelf. ![fill corner](opensource/shelf_01/corner_full_01.jpg) ![fill corner](opensource/shelf_01/corner_full_02.jpg) ![fill corner](opensource/shelf_01/corner_full_03.jpg) ![fill corner](opensource/shelf_01/corner_full_04.jpg) ### Print - Printing time per corner: ~30 minutes - Weight: ~16g *(~62 pieces per 1kg spool of filament)* *** # Corner side This connector has 3 openings and is used for the outer parts of the shelf to create clean edges and for the base so the shelf can stand flat. ![side corner](opensource/shelf_01/corner_side_01.jpg) ![side corner](opensource/shelf_01/corner_side_02.jpg) ![side corner](opensource/shelf_01/corner_side_03.jpg) ![side corner](opensource/shelf_01/corner_side_04.jpg) ![side corner](opensource/shelf_01/corner_side_05.jpg) ### Print - Printing time per corner: ~25 minutes - Weight: ~13g *(~77 pieces per 1kg spool of filament)* *** # Shelf segment This is not a complete shelf but a segment. You can decide how many to print depending on what you want to place on it. The shelf is provided as a contour design, so you can adjust the thickness in your slicer if you need stronger shelves. ![shelf](opensource/shelf_01/shelf.jpg) ### Print - Printing time per segment (10mm width): ~18 minutes - Weight: ~10g *(~100 pieces per 1kg spool of filament)* *** ## Open Source DIY Concept This project is part of our **DIY Project Depot Freebees** initiative: simple, budget-friendly, and customizable designs for everyday use. The hexagon shelf is made using basic cable channel tubes and very small amounts of PLA filament, showing how even leftover filament can be turned into useful furniture. *** ## License ![diy_project_depot_license_pictogram](opensource/diy_project_depot_license_pictogram.webp) ✅ Personal Use – You may download, print, and use this design for your own projects. ✅ Modification – You may modify this design for your own personal needs. ✅ Attribution – Please credit DIY Project Depot / diyprojectdepot.com when sharing your work. ❌ No Redistribution – You may not share or upload these files (original or modified) to any platform. ❌ No Commercial Use – You may not sell the files or physical products made from them.
