Support me on Ko-fi: https://ko-fi.com/elizabeth3d The Hot Air Balloon Piggy Bank is a working coin bank for your travel fund: the woven wicker basket is the money box, and the balloon rides above it on four braided ropes. Design Concept Save up for your next adventure. The balloon prints in three color bands (red, cream and sky blue) that the CFS switches automatically, so it needs no painting. Purpose Drop your coins through the slot on top of the basket: at 30 x 5 mm it takes every euro coin, from 1 cent to 2 euro. When it's time to travel, unscrew the cap under the basket with a coin and pour your savings out; a funnel inside guides the coins to the opening. The cap has a four-start thread (it opens and closes in less than a third of a turn) and sits flush, so the bank stands flat. Print Settings - Size: about 131 x 131 x 277 mm

- Printer: Creality SPARKX i7, 0.4 mm nozzle. Material: PLA. Layer height: 0.20 mm. All inside the 3MF: just open it as a project

- Plate 1: the balloon in sky blue, cream and red, standing on its flat bottom collar, with tree supports from the build plate only

- Plate 2: basket, cap and four ropes in warm tan, no supports: the basket upside down (top face on the plate), the cap flat side down, the ropes on their flat side

- Do not scale it: the thread is sized for 100%

Assembly The four ropes are numbered and each one is cut for its own corner, so keep them in the order they print (Rope 1 is the one nearest the front of plate 2). Seen from above, fit them counter-clockwise, Rope 1 and Rope 2 on one long side of the coin slot and Rope 3 and Rope 4 on the other, pushing the peg at the bottom of each rope into its socket on a top corner of the basket. Put a drop of glue on the top end of each rope, where it hugs the rope ring of the balloon, set the balloon on the ropes and let it cure. Screw the cap in with a coin in its grip slot until it stops; turn it the other way to empty the bank.
