I downloaded this model from: http://www.pluto.dti.ne.jp/~naka/ and scaled it from 1:50 to 1:32 to fit with the V1 and V2 rocket.
After downloading and resizing, I removed all the green colors from the drawings.
The model is then printed on green 160 gr/m2 paper. The paper is green throughout the whole sheet. So painting the edges after cutting is not nessecary.
When this model is finished, I'm going to build a diorama (not a paper diorame but a classic diorama out of styrofoam, wood and plaster).
In the mean time, I ordered scale 1:25 of GPM the:
Sd.Kfz 250/3 "GREIF"
Sd.Kfz 251/1
PzKpfw III Ausf. G
Pak 40
With these models (when finished in a few months/year) I'm going to build a Deutsches Afrika Corps diorama.
