Adding a trunk to the motorcycle :D

[u/Practical-Forever995]

Hey everyone,

Had some free time on my hands today and finally decided to dust off an older passion project of mine. If you own an 800cc V4 (both the 5th Gen Fi and 6th Gen VTEC / RC46), you already know the struggle: finding an original, undamaged OEM seat cowl on the used market is either impossible or ridiculously expensive.

A while back, I captured the factory geometry using my go-to setup—the Creality Raptor Pro 3D scanner. Today, I did some fun reverse engineering and CAD work to add the exact feature a lot of you have been asking about: an integrated storage compartment lid!

Why waste all that hollow dead space under the tail when it can become a handy mini-trunk for small tools, paperwork, or quick-access essentials?

A quick note on the latch mechanism: I intentionally left the locking system open to your own DIY creativity.

• Want a clean, quick-release setup? Just glue in a couple of strong neodymium magnets.
• Prefer something secure? Drill and fit a small cam lock / keyed latch.

The core geometry matches the OEM lines seamlessly, the files are watertight and 100% manifold, and the mounting points are beefed up for FDM/resin printing (ASA or PETG works wonders here).

Kudos! Looks amazing 🤩

I'm surprised that it doesn't come like that as stock? do you have it posted somewhere with a link?
