Pressurized Ink Cartridge Adapter for Tactile Turn Short Bolt Action Pens

prusaprinters

A simple adapter for using a Rite in the Rain (No. 37R) or Fisher Space Pen ink cartridge in one of Tactile Turn's “short” Bolt Action or Side Click pens.There are three different adapters, one for the Bolt Action Pen, one for the Slim Bolt Action Pen, and one for the Slim Side Click Pen.The adapters are designed so they provide the same amount of ink cartridge tip protrusion (from the body of the pen) when used with their respective pen model — 2.9mm +/- ~0.15mm (most of the variation is in the ink cartridge itself; I used the same ink cartridge to measure all three and had a total variance of 0.04mm between all three).Printing Considerations:A 0.25mm nozzle is recommended, but as long as you're slicing with Arachne, a 0.4mm nozzle will work just fine. If you're not slicing with Arachne, it will create a lot of weird artifacts for a 0.4mm nozzle due to the small size of the adapter.0.1mm layer height (regardless of nozzle size).3 perimeters.20% infill (irrelevant for 0.4mm nozzles with 3 perimeters; no infill).1mm top/bottom thickness (also irrelevant for 0.4mm nozzles; no infill).Choose your favorite material; I used PETG. Change Log:02NOV2022: Updated cover photo.05JAN2023: Added new model for Short Slim Side Click pens; revised/updated description.
