The other option now is to get a reasonable 3D printer. The pics below are from a creality runout model I just got. This one is the plastic roll type so
small detail is more difficult sometimes compared to a resin printer. With the pricing now having both is also an option.
All the prints shown are
free on the internet. There are literally thousands of items available. Purchased files can be had cheap and many are exceptional.
These ones are different scales for tests and for use in games.
The Jagdpanther with the paint on it is 1/100 scale.
The statue, Dalek, and Cyberman are 1/35 ish - dalek is not finished as I haven't glued it's eye stalk or plumbers plunger on yet.
The horse is no particular scale.
Oil drums 1/72 but they seem a bit big.
Romulan warbird is something or other scale.
The frigate is 1/1200th for Napoleonic ship gaming - print one, make a mould from window silicon, pour several more
using epoxy resin and it's done.
The trucks, Daimler Dingo and Matilda are 1/200 scale. I downloaded a few packs of vehicles that are in the Jagdpanther scale (1/100)
and scaled them down before printing. The packs I downloaded contain more than fifty WWII vehicles and variants - not bad for nothing.
Print costs are low and the speed of these newer ones is good - the Dingo was a 5 minute print.
The oil drums are the the type of thing that is the most interesting. Accessories are where the cost for a diorama can really bite. Tools,
boxes etc plus some figures adds a lot. These printers cut those costs dramatically and they are really easy to use.
Apologies for the pic quality - it's Sunday.
