Ah — 3D printing changes the shape of the answer, so let me be straight about what you’d actually need.
Measurements alone won’t get you a printable part. You need a full 3D model, and there’s no way to build one from a handful of dimensions taken off a bike — the cowl is a compound-curved shell with the mounting points in specific places. So it’s really one of two routes:
- Scan or measure an original cowl properly. If you have one (even a damaged one), photogrammetry from a good set of photos, or a 3D scan, is the realistic path. Same if a friend local to you has one to lend.
- Find an existing model. I searched the usual places (Thingiverse, Printables, Cults, the STL meta-searchers) and I couldn’t find a VF1000R seat cowl model published anywhere — so I don’t think there’s one sitting there to download.
On printing it: the cowl is almost certainly bigger than a typical hobby print bed, so plan on splitting it into sections and joining them (or printing a plug for a mould). ABS/ASA takes filler and primer well if you’re painting it.
Two things on the forum that might save you the CAD work:
- Fabnorman modelled VF1000R parts in SolidWorks and shared the files — see RH fork adjuster cap FE and Fork leg plastic cap 3d print. He’s the member most likely to have an informed view, and there’s a general thread on what’s worth printing at 3D printing possibilities.
- Italian Mold Lab already make VF1000R plastics — members have bought from them (Seat cowl interchangable?, Accessory plastics). If your goal is simply a good cowl in hand, that may beat modelling one from scratch — worth a look before you commit to CAD.
If you do decide to model it, say which R you have (RE/RF/RG) and whether you have a cowl to work from — I can point you at the parts breakdown so you’ve got the fixing detail right.
