Shotshell Holder 8Q

Simple 8Q shell holder with additional 1Q space for for chamber-load.
Created with twin load in mind, quad-load is managable, but not really conveniant.
Mounted on base from FMA 4Q Independent Shell holder.

Update 2021-01-02:
- new version of upper part: 8Q_twin_UP_12_19.4.stl - the "holder" part is now 12mm instead of 14mm high with internal diameter increased from 19mm to 19.4mm. You need less force to pull the shells with this setup. Previous "upper" part can be reused as a new "lower": for me grabbinf first round from lower part feels more natural.
- Quad-load version uploaded
- Better pictures of printed parts
