Hello,
I would like to share my new project - Panzefaust 30 "Klein". There is Panzerfaust 60 on thingiverse, but there is no 30, so i decided to draw one based on drawing found on internet. Suggested printing orientation are pictured above. Tolerances to fit parts are 0,3 mm. Parts needing supports are: "1"and "Kapsel". There should be no need for supports on rest parts.
If You have problems printing part 5 (its thin - 0,3 mm) - You can adjust its thickness simply in slicer, by increasing its dimensional scale in one direction (i had no problems on Ender 3 though).
