Piggy Bank, Coin Bank

thingiverse

Revised instructions for two versions of a piggy bank are provided. One has an opening on the bottom and requires supports, while the other is a one-piece model without supports and is printed hollow. Both models measure approximately 5"x5"x5" with a coin slot that can hold a quarter. Coins can be shaken out from the two-piece version, which features a friction fit plug that should be glued in place for removal. The one-piece version cannot be opened other than by cutting it open. Print settings include a Prusa, Makerbot Replicator 2, and an Ultimaker printer; no rafts; supports for the two-piece model; a 0.2 resolution; 15-20% infill; and three layers on top, bottom, and sides in PLA for ABS durability. The one-piece bank file is named "8-17 One Piece Bank no supports.stl," while the two-piece version consists of a body and plug file titled "8-17 Bank body with bottom hole" and "8-17 bottom plug." Post-printing involves removing supports from the two-piece model, gluing in the plug, and skipping post-processing for the one-piece version. The designs were created using Spaceclaim software, featuring 45-degree angles on horizontal surfaces to eliminate support needs on the outside. These instructions are intended for an Ultimaker 2 printer by Printer Brand Ultimaker. Note: Simplify3d estimates a print time of over 20 hours for the two-piece model on a Prusa in Fast Mode at 15% infill.
