Threw this together or fun.

The scale is slightly smaller than a Glock 19 by ~10%, so a slicer setting of 110% should make it about the same. I wouldn't recommend scaling much past 130% unless you have bigger hands

LORE (if you can call it that): It's smaller frame lends itself well to the role of concealment or as a backup for when all else fails. I had imagined this as being near future LEO or Merc weapon being "chambered" in a caseless .357 round to prevent crime scene contamination or unnecessary evidence. It may be favored by criminals for the same reason. And yes you do still want an extractor for caseless rounds, never know when you may need to clear a jam or just unload for safety.

Doesn't Matter

.15-.2mm Works Fine

2-4 Wall, 25%+ Infill (35% Grid Is Very Solid)

Print orientation I've been using is the angled flat face on the back of the slide, against the bed with tree supports.
