This is my design of an intentional technical-looking hook to hang clothes or bags to a clothes rail. I designed it for minimal material use with a good compromise of stability.
Update 2022-09-27: Added D18 for Ikea furniture. Added labels to model images. Added visual PDF catalog.
Dimensions
The part number and file name have the following format:
LR2258-W<hook width>-D<rail diameter>.3mf
Hook Width and Height
Dimension W
defines the width and also the height of the hook. The number after the letter in the filename is the dimension in mm. The height depends on the width and is calculated by multiplying the width by two and adding one millimeter.
Clothes Rail Diameter
Dimension D
defines the nominal diameter of the clothes rail. The number after the letter in the filename is the width in mm. The hook works with round rails, as well as with rounded rectangle rails. For the latter, the maximum height is twice the diameter. The hook will not slide on the rail easily if the height is larger.
Visual PDF Catalog
There is a PDF LR2258 Catalog.pdf
that contains images of all model files, dimensions, and filenames.
About the Design
With this design, I aimed to create a technical-looking hook that uses minimal material but still provides good stability. The hook is perfectly symmetrical, so it does not matter which end hangs on the rail.
To create perfect-looking prints, I designed the geometries for 0.4mm nozzles at a 0.2mm layer height. This combination produces the best results, as all walls print with four evenly spaced lines. The dimensions I used also work for 0.6mm or 0.8mm nozzles with the specified layer heights. I didn’t test prints with these sizes, but they should also produce great results.
The profile is an almost perfect “X” with 45º angles. I added two rounded corners in the middle to reinforce weak points. Additionally, there are ribs at critical points, forming a complete rectangle. These prevent distortions when weight is applied to the hook.
PLA is not Ideal for Heavy Weights
PLA is not an ideal material for large weights as it will slowly but permanently deform over time. If you print these hooks with PLA, use them for light weights only.
Maximum Weights
The example print “LR2258-W12-D15”, printed with PETG, will easily hold a bag with 3kg or more. The maximum weight depends on the chosen hook width and material.
