About this 3D model

Designed to securely carry two FlexPen®. Design consideration: Each pen stored in their individual chamber to avoid misplacement of unused pen while using another. Cutout allowing user to verify the presence of pen(s) in the case, and the color code of the pen. A shelf to elevate the injection button, so that even pushed down hard the button will not activate. Caps are secured via lanyards to prevent them from getting misplaced. Printing consideration: Position the main body so that the opening of the chamber with the injection button shelf is facing up. Print the spacer, add a drop of super glue, and insert it into the chamber without injection button shelf. This approach allows the upside-down chamber to have a nice finish without the need of excessive support. 4x heat theard inserts are required, McMaster-Carr part number 97171a120 . 4x 4-40 socket head screws are required, length between 1/4 and 3/8. Make 2 lanyards of suitable length, make sure the loop is bigger than the screw thread but smaller than the screw cap, McMaster-Carr reference . Apply a drop of high strength Loctite (e.g. 271) and install the lanyards and the screw. Install the screw so that the lanyards can turn freely. Let cure.
