Pen holder for CNC or 3D printer

thingiverse

This is a self-sprung pen holder remixed from scratch. The goal is to create an OpenSCAD file that allows you to increase the width and depth while keeping round (and now adjustable) screw and nut holes, suitable for deeper pens. Default settings are optimized for maximum 15mm diameter pens. The holder mounts to the cutting/printing head with two screws spaced 20 mm apart. To produce mounting bumps, simply glue it into a platform with matching holes. I use this platform on my Da Vinci 1.0a. Print Settings: Printer: XYZ DaVinci 1.0a with Repetier Rafts: No Supports: No Resolution: 0.25 Infill: 15% Notes: A brim was used to prevent warping. Post-Printing: The 120% size version fits a 15mm fabric marker too tightly, so some sanding may be necessary. Design Process: I converted the original STL file to SCAD using a python script. I located the holes with Meshlab and wrote SCAD code to fill them in and create new ones, allowing for adjustable screw and nut holes suitable for deeper pens.
