I collect many items related to Loch Ness and its Monster, so I came across this nice little item on eBay which is a 3-D print of the loch based on the 1903 bathymetric survey done by Sir John Murray. The description runs thusly:
3D Printed High Detail Bathymetric Survey Model of Loch Ness created from original info obtained in 1903 by Sir John Murray.
This model gives a unique view of what the Loch looks like under the water.
1000mm version - Scale 1:38,000 Horizontal & 1:19,000 Vertical.
A large scale model of this is on display in the Loch Ness museum.
Printed in Glow in the dark green or blue PLA.
All models include a recessed area at the bottom for a UV LED strip Light. (included)
This will come in 3 sections that are not fixed together.
It's not my cup of tea, but others may be tempted to spend the £88 on it. There is also a cheaper but smaller unpainted model listed by the same seller here.
