Kawasaki Z H2 Woolich Logbox M v3 & ZT-3 Mount

This is a mounting bracket for a Woolich Racing Mv3 Logbox and Zeitronix ZT-3 O2 sensor box for the Kawasaki Z H2.

It tucks these units in the vacant space underneath the front seat latch (for my 2023 UK Model anyway) and provides access to the Mini USB socket on the Logbox.

You will need 5mm longer mounting bolts. I believe that the stock numberplate bracket uses M6x14 so go for M6x20 button heads and stick a 1mm washer underneath. I have a tail tidy so couldn't check.

When printing will need supports enabled and make sure you select 'supports on baseplate only' as there are internal channels for the cable (zip) ties and filling them with support material will make you curse.

To assemble, first fit the ZT-3 and secure it with a cable (zip) tie. Loose fit the cable tie for the Logbox and cable retainer (if required). Connect the cables to the ZT-3 and slide the assembly into place. Fit the retaining bolts/nuts. Connect the RJ12 cable from the ZT-3 to the Logbox and the cable from the bike's loom to the Logbox then pop the logbox into place; it's a snug(ish) fit and should just clear the frame seat bracket. Tighten up the cable tie on the Logbox.

I suggest printing in ABS (ABS+ can work well on non-enclosed printers) or some other heat tolerant material although PLA would probably do as it's unlikely to get that hot in this location (don't blame me if it melts!).

I've included the Fusion360 file for anyone that wants to tweak it.

Enjoy.

Edit: Someone commented that they'd like to see some rubber underneath the mount to isolate the Logbox a bit (my Logbox has survived a number of years being cable tied to my ZX10R but I guess it can't hurt). So there's now a "with TPU" version that's had 3mm sliced off the bottom and a 3mm thick model for a TPU damper (or you could just cut  up a bit of 3mm thick rubber).

Or.... you could just print the whole thing out of TPU or similar. If you do, I suggest you use modifiers in your slicer and make the slots that the bolts go through solid (100% infill or a million walls) so they don't crush down when you tighten the bolts.
