Dual-Spacing 450 Ω Ladder Line Spacer Sprue
A sprue of six snap-on spacers for homemade open-wire ladder line. Each spacer has two pairs of side-entry wire seats: 34.8 mm apart for about 450 Ω with 14 AWG (1.63 mm) bare copper, and 43.8 mm apart for 12 AWG (2.05 mm). The 2.4 mm seats sit behind 1.7 mm entry slots, so you can press spacers onto wire that is already strung instead of threading them on beforehand. The sprue measures 64 x 80 x 5 mm, and each spacer snaps off its tabs. For a line that lives outside, print it in PETG or ASA.
