Two days ago I decided to add some details to Mendeleev Tank. Note that exaggerated ladder piece will be 1 mm thick after printing.
Here are updated tank specs:
Maximum speed: 10-15 km/h on plans but 3-5 km/h according to modern research
Armor: 150mm front, 100mm sides and rear, 76mm roof
Armament: 120mm 1892 Canet naval gun
Maxim Machine Gun
