Featherboard 5/8in Guide for Harbor Freight Featherboard

Harbor Freight has a very nice, inexpensive featherboard for their table saws. Unfortunately for me, I already had a Skil saw from 20-ish years ago with a narrower, 5/8" guide slot versus the 3/4" the HF featherboard was designed to. So, I whipped out Fusion 360 and cloned the HF model, except 1/8" narrower. https://www.thingiverse.com/thing:673323 appears to have been made for the same reason, except in OpenSCAD. For me, Fusion 360 is far easier to do this kind of model in. Chamfers and Fillets
