at Easter, Asiatam had an offer from the "Opel Maultier" chassis.
I could not resist....

The package came a few days later ..
But what do I do with the chassis?
I had an idea: Sd.Kfz. 4/1 "15 cm Panzerwerfer 42" build from scratch
Ordered the book Nuts & bolts volume 30 for reference...
The small parts, hatches, motor and 15cm nebelwerfer are designed with Fussion360 and printed on a Anycubic Mega.
The Hull is build from Poly Plastccard, and i apply arround 200 rivets..
