DL the plans/templates from JimZ's site, and scale up & print the patterns as appropriate.

My Super Orbital Transport is BT-60 main tube, making it a 1.68X upscale. The orbiter I built is 29mm tube, which is very close to perfect (1.21” OD vs. 1.23” OD at scale factor). A BT-55 is a bit too large.
I took my original templates to Kinko’s (this was back around 2010) and had them enlarged and printed on cardstock-like 11x17 paper.
I bought a BNC-60K nose cone from eRockets (original nose cone is a BNC-50K), and I turned my own orbiter nose cone.
Most of the transporter is basswood, the orbiter is all balsa. Tango Papa made my decals.
First picture it is next to my standard OT. It looks a lot bigger than the scale factor of 1.68X, I think. I flew it at NSL-2017 in the Upscale Competition on an E18 reload in the 24/40 RMS. Perfect motor for it! It lifted aggressively, and reached an altitude whete you could see ejection clearly, andthe orbiter detach. Second picture shows it on my 20mm rail prior to liftoff.
