I really liked the original model on here and found myself putting with it a lot, so I decided to refine it a bit. I added a copper faceplate(changed depth of faceplate to 3mm vs 6mm) and created small front side cavities to accommodate 4 additional 0.25 oz weights. I also filled in the rear cavity that wasn’t usable for weighting.

I’ve included a bottom plate without holes, as I found the snap fit held well with a bit of epoxy. You can use aluminum, steel, copper, or any material you prefer for the face, I just went with copper. You will need to cut it to shape and belt sand it down to size to fit. With a copper setup, the putter came out to exactly 400 grams, so you can adjust the weights to suit your preference. I used a shaft from temu with a .370 tip.
