DNA Double Helix Headphone Holder

thingiverse

Inspiration: I had just finished my first year of Biophysics PhD and wanted a personalized headphone holder for my desk. I was not satisfied with anything available and had the idea to include DNA in the design. This is what I eventually came up with. I know technically I have the incorrect number of NA per revolution but this compromise made the headphone holder function better. This file is OC by me. The base stand and the DNA do not need the same settings. For the Base: I chose black but the color is up to you. You dont need more than 20% infill and there is no need for supports. For the DNA. This was stupidly tricky to print out properly. I generated lots of spaghetti so I dont suggest trying this unless you know how to troubleshoot a print. I used 50% infill for mine but I would suggest no less. 100% is preferable. 50% might work if your headphones are lighter than mine (Bose QQ 35 2's). If you have access to tree supports i would highly suggest turning them on. They help make sure the overhanging bonds print without drooping. the supports are going to be hard to remove so take your time. **If your printer is a bed slinger** Print the DNA super slow. due the the nature of the design you might find the DNA oscillating at high layers. I had a few failed prints because the oscillation caused the print to bump into the nozzle and dislodge the whole thing. Print at normal speeds up until the 5th or 6th nucleotide, then drop the speed as much as you can. Patience is key.
