This bank was made to give some visual entertainment when you put a coin in the top and it slides to the bottom of the bank.the neck should be printed with no smaller than a .8 nozzle at 1.1 mm set on vase mode, single layer. The base of the neck should be printed at least 5 layers thick to hold the coins. (a 1.0 nozzle may be better but I printed with a .8 and it turned out well.) Pet-g worked best for the neck. The hand can be printed in anything you wish but if you are going to acetone your ABS you will want to print 4 to 5 layers thick ( that is the hand in the picture, ABS)
The top of the neck trimmed up well with a dremel tool but in the past I have used a flat file . I would not recamend using a razer knife, the pet-g may split . For printing, neck is 279 mm x 142 mm. see it here: https://www.youtube.com/shorts/jo_a57KPUYs
