Glock Magazine Spring Jig (15,17,20,30 Rounds)

This spring jig was inspired by "Glock Mag Spring Jig" 0xdb1b I needed a 30 round version, and added start holes for 15, 17, and 20 round springs as well. This was a quick model so it may have some flaws but I find it to work well so far. Please let me know what can be improved.To use, place the end of a piece of spring wire no bigger than 1.3mm into a start hole and then begin wrapping upwards towards the top. Pilars or a vice may make this easier, but I find it's easy enough to do
