removable flock swab

IMPORTANT UPDATE: Cotton is completely unusable because it's a natural material that can damage RNA samples. Unfortunately, this idea isn't very useful as cotton can easily contaminate the sample. I use clear PETG for its excellent durability against UV radiation. Infill density is set at 25%, and layer height is precisely 0.2mm. To create a removable flock swab holder, I designed it to hold ordinary commercial ear sticks, perfect for situations where flock swabs are unavailable. Here's how you can use this holder: 1. Remove the cotton from one side of the ear stick. 2. Sterilize the ear stick thoroughly. 3. Insert the ear stick into the holder. 4. Use the holder as needed. 5. Remove the stick after use and save it for further testing. 6. Sterilize the holder again to prevent contamination. Important Note: As I'm not a biologist, I can't guarantee that this will work in medical contexts.
