Topology Optimized Banana/Headphone Hanger

• Edit: I need to redesign the top interface, it is currently to weak!

Topology Optimized Banana/Headphone/Whatever hanger.

Designed in ANSYS 2019-R2

• I remeshed the body, but didn't smooth or resurface it.
• I kinda like the computer generated organic look to it, and I think it makes a cool print, almost vase like if you set your Z-seam correctly.

Has removable hanger pieces, so you can customize and create your own.
The dimensions for these can be found in the images, but remember to consider tolerances. (The dimensions shown are hole size) (I used 0.1 mm tolerance for my printer)

Total size: 160 mm x 170 mm x 199 mm

I'd maybe scale it larger in the Z direction if you are hanging larger objects.

Print Settings:

• CR-10
• AMZ3D Black PLA
• 212º
• 0.4 mm Nozzle
• 0.2 mm Layer
• 0 Infill
• 0 Support? some bridges are rough.
• 3 Outer walls

∆ I actually printed this with 0 infill.. I was kinda shocked it worked, The only issue is the bottom 5% where you have some bridging, so pay attention for the first little bit of the print.

∆ There's definitely some sketchy bridges/overhangs, so consider adding custom supports. For my first print, I didn't have any supports, and had a couple areas that needed clipping.

Hanger Settings:

∆ You can use a triangle which has a ~7 mm base, by ~10 mm tall, by 10 mm deep. (pictured)

Notes:

∆ This can be a challenging print, so make sure everything is dialed before trying!

∆ You might want to add custom supports for the bottom 5%, its a long overhang..

Versions:

V1: I printed this, as well as the two hangers, but the slouching/tolerances are a bit off between the two bodies. You can either scale the hanger parts smaller, or wait for my edit.
