There are plenty of other coin holders for UK coins on Thingyverse, but if like me your also an international millionaire playboy, you just don't need the smaller denominations.
So I made this, it only holds £0.50. £1 & £2 coins, infact its 10x £0.50 & £2 and 30x £1.
I designed it to sit at the back of a desk draw at
work my mansion so its pretty compact, coins are held in place and will not fall out the front, but will lift out pretty easily.
Printing is easy as its a basic model, Cura's guess was around 5.5mtr filament and that's using fairly standard settings so good for using up short lengths.
Hope this helps someone.
