Heroscape Wound Marker

Description:

A no-frills wound marker for the game Heroscape. Based off measurements of the original Heroscape wound marker. Slightly modified internal geometry to optimize for FDM 3D printing vs the original injection molded part. Same outer dimensions as the original Heroscape wound markers, and is fully stackable with them as well.

Slicing Instructions:

Default PrusaSlicer settings should work fine. I designed this to be printable without supports, so I recommend no supports. 

My initial prints are done with a 0.4 mm nozzle and 0.2 mm layer height, QUALITY. I tried 0.25 DRAFT with the 0.4 mm nozzle and the results could not really be differentiated. A slightly more pronounced seam line was about the only difference.

If you want a lot of them, printing in sequential print mode can help avoid stringing. The downside is space. You're limited to 16 of them on a MINI build sheet with sequential spacing.

Gcode Files:

Since I own a Prusa MINI+, I've also included .gcode files for a single wound marker, as well as a plate of 16 wound markers. More could be stuffed on a plate, but I used sequential printing for a cleaner print with less stringing and oozing, and much more space between objects is required when printing with sequential printing vs normal printing. 

Please note that while I tested both .gcode files on my own Prusa MINI+ that my MINI is stock. Print head modifications can and will change clearance required for sequential object printing, so use care if using my sequential object printing file if you have modified your MINI print head!

Background - Why I Made This:

Whenever we play Heroscape, we find ourselves quickly running out of wound markers from the original game's stockpile. 3D printers are great for oddball, simple items like this. 

Originally, I tried to print the one from aschlauch on Thingiverse, but found it needed supports due to the stacked empty cylinder shape inside - which is how the original was made. But the original was injection molded. Aschlauch appears to have simply scanned the original one with a very nice 3D scanner. 

My goal when designing 3D parts is to avoid needing supports. This is good engineering practice in general - design with the manufacturing method in mind. So I pulled out a pair of calipers, measured an original Heroscape wound marker, sketched some dimensions on a piece of paper, fired up FreeCAD, and modeled up a slightly modified design in less time than it took to write everything you see on this page.

Final Thoughts:

I've included the .FCStd file for FreeCAD, in case you'd like to modify this for any reason. For this file and every other file on Printables and elsewhere, please do the right thing and follow the author's license stipulations.
