When pen-plotting, the default ink reservoir feels small, and for larger plots it needs to be refilled. A friend asked me to print him a longer one.
It's a simple tube generated in Replicad. I printed them in semi-transparent PETG (brand unknown). Transparency is handy for checking the ink level. The 7.6 mm version works best on my printer - it's a really tight fit and no ink leaks - but feel free to experiment.
All provided models are 100 mm long, with inner diameters of 7.6, 7.65, and 7.7 mm respectively. If these sizes don't work for your printer/filament combo, you can edit the model online to change the radius and length.
You can generate multiple versions by updating the radii array, for example: const radii = [3.85, 3.9]. The program will automatically add small markers at the bottom to differentiate them.
