AK barrel press

Parts needed.
1x 3' 1/4-20" threaded rod
2x 1/4-20 coupling nuts
2x 1/4" SAE washers
2-3 pennies and or dimes for shims

Print with several walls and 100% infill. Regular pla or abs works fine.

Depending on printer accuracy the printed nut may not thread onto the barrel. Can scale it up a percentage or two if needed. Otherwise print the bushing which slides over the threads.

Here's the thread on its use.
