3D-Printed Screw-In Front Lenscaps With Optional QR Code

myminifactory

My design https://www.myminifactory.com/object/33084 was created with speed and simplicity in mind, as a 3D-printable screw-in front lenscap that can be customized to your liking. This design uses less than $0.15 worth of materials for a typical size lenscap, yet it works well and even doubles as a color reference. For more details on how to make one, check out this Instructable: http://www.instructables.com/id/3D-Printed-Screw-In-Front-Lenscaps/. This updated design offers three key improvements, which are demonstrated with the green cap: The new OpenSCAD font support allows you to choose a font for labels and now supports up to three lines of text. Unlike previous versions, this one doesn't rely on the Write.scad library. You can also specify the rotation of the screw thread to ensure that the text labels remain upright when screwed into your lens filter thread. This design integrates a QR code generator from http://www.thingiverse.com/thing:258542, enabling you to print a QR code label inside your lenscap. Why do this? For instance, you could use it to identify which adapted legacy lens you're using by taking a photo of the lenscap whenever you swap lenses.
