Size 5 feed for sport fountain pens

prusaprinters

<p>A feed designed to fit in a sport fountain pen to enable the use of standard bock size 5 nibs.&nbsp;</p><p>The feed features an ink snorkel design meaning that only the tip of the feed needs to be submerged in ink when filling making the process tidier.&nbsp;</p><p>This is designed to be printed end-on, directly on the build plate. As such it requires a well tuned printer with pre-exposure delay appropriately increased. If using a chitu-powered printer UVtools is necessary to create an empty first layer.&nbsp;</p><p>Using the right resin and exposure times is needed to allow the ink channels to print properly - they are 150um wide each, so around 3 pixels of a standard desktop printer.&nbsp;</p><p>Alternatively you can try to carve them out afterwards with something like a feeler guage, but I suspect that wouln't end up very clean.&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>I used anycubic grey ABS-like+ resin , with a 2 base layers each exposing for 2.5x the standard layer exposure and no transition layers. This was supplemented by a 30sec wait time before cure for the base layers afnd a 5-15 second wait ime for the remaining layers, using UVtools' ‘wait time before cure’ function to vary it depending on how loaded the build plate is.&nbsp;</p><p>&nbsp;</p>
