Downspout Extension Stake-Down Saddle
This saddle straps a downspout extension to the ground so it can't blow away or get kicked off. It has a 90 x 62 mm opening, which takes a 2x3 in rectangular extension or a 3 in round corrugated one. Each 28 mm foot has a 6.5 mm vertical bore for a tent peg, 6 mm steel rod or #10 screw. The part is 156 mm wide, 20 mm deep and about 38 cm³. It prints on its side, so ground-pull loads run through the layers, not across them.
