Nice! 3D printing sounds great but how do you know the unstrung custom pallets will fit on your hairpin? ie what are the inside dimensions of the printed pallet?
Before i start anything on the handle i measure the dimensions of the graphite hairpin i can see inside the buttcap, and at the top of the handle using the groove i cut. Just to know that if i stuff up badly, i can take off the molded handle and put Head pallets on. But Head pallets measure about 17 x 25mm on the inside and are pretty small, they wont fit on most racquet hairpins..... but the RF97 seems to be one of the rare Wilsons that have a hairpin handle small enough for the Head pallets to fit, and i think they must have done that deliberately.
That’s the best part the already have all the different frame hairpin dimensions in a database. You just tell them the racquet model and what shape you want the grip to be, and they’ll print it.
