Art Marker - Takes Copic nibs

thingiverse

My spouse wanted to buy a bunch of Copic markers because she loves their super brush nibs. I've been trying to teach myself 3D design, so I decided to take on the challenge of designing a printable marker that can accommodate their nibs. You can use the filling from an all-cotton tampon as the ink reservoir to hold the liquid. Be sure to clean out the hole slightly to ensure a snug fit for the nib. The nibs don't need to be fully seated to function properly and are easier to remove if they're not pushed in too far. You may also need to clean up the first thread on the bottom of the marker to get the bottom cap to thread on securely. *Update*: I've uploaded a new version (V2) that's a bit bulkier, but it seals better than before. During testing, the marker eventually dried out and needed to be rehydrated with alcohol. I'm looking for ways to solve this issue or at least extend the time between refills. To print these markers successfully, use low layer heights and include at least one thick inner wall. This will help prevent leaks and evaporation. I used 0.05 layers with a width of 0.4 for the outer walls and 0.65 for the inner wall. The marker in the picture has stayed hydrated for over a week without showing any signs of drying out. You could also try using 0.1 layers, but 0.2 might be pushing it - you could use two thick layers to compensate instead.
