this 3d model is an inspiration from the Zeta gundam launch pad model. I wish bandai would sell it separately, but apparently not. Included is the 1/144 version and the 1/100 version. FDM printer and resin printer friendly.
You can attach an existing bandai model stand to this pad. You can also print one from the many models available on this site. Please feel free to upload photos of your mecha for me to see!
1/100 pad is 140mmx260mm1/144 pad is 183mmx106mm
