This model comes in two sections, allowing you to easily replace the sandpaper as required. These things are cheap enough to print so that you could have multiple shapers with different grit if you're a real artiste with your snooker cue tip. Simple unscrew, push out, and replace.
Cut your sandpaper to 72mm x 27mm.
As with any screw, fidelity is important in order to create something usable. For the main part, I suggest using 0.15mm layer height for the first 5mm to create a detailed screw thread. After that, you can switch to 0.3mm to finish the model more quickly. As the model has a relatively small surface area, I found I needed to create a brim to have enough stickiness; I used 8 outlines. The model isn't currently all that forgiving for the first layer, so you need to have a well calibrated printer to get that insert hole for the sandpiper right from layer one. You definitely don't want a crushed first layer or it'll be difficult to feed, though you might be able to help it with a craft knife if you have issues. The same goes for the screw entry hole, which isn't chamfered on entry, thus necessitating good calibration.
For the screw part, I printed the whole thing at 0.15mm layer height to again detail the screw well. I also wanted a strong screw, so I infilled 100% from 1.4mm height upward.
Both parts are already oriented for printing.
