Piggy Bank Safe

With Pig and Boar models

100x100x100mm Case + Door (adding 12mm to length) with a gear mechanism
Optional 12cm long version of a Case

Printed in parts without supports
Assembled without glue

Model is free for personal use only
If you want to sell prints of this model I can prepare a Commercial Licensed version - or you can join my Commercial Membership on MakerWorld or Thangs (check my bio for a LinkTree)

2 versions of door opening mechanism
with simple gears wich will work easier and should be stronger
or in bistable version - it is stable only in closed or opened position, when rotating you are pushing a spring - PETg may be better for this mechanism but it works fine with PLA

Additional versions for printing without infill
Optional springs for clicking sound
Addon to optional fill the coin hole - to work as a simple Safe not as a Piggy Bank

Doesn't Matter

No

0.4mm nozzle
0.1 or 0.2mm layer height
3 walls
1.2mm of top layers
1mm of bottom layers
printed with transparent PLA (PETg may be better for bistable mechanism and hinge pins)

Brim for HingePin may be usefull

As a test you can print inner and outer eyes first
You will check if your printer and slicer settings are right for this project
If it will be too hard to assemble you may try using Horizontal Expansion / XY Compensation with negative value (start with maybe -0.02)
If it will be too loose use positive values
If everything is fine so the rest of the parts should be fine too

All parts may be printed without supports but if your printer doesn't have a good cooling you may need some when printing a Door
You can print a Door with a GearWheel as support - there is a sepparate part for this

Addons are with a flat rectangle around it to proper line it up with a base part
Ignore errors and don't try to fix them
Merge addon with a base part in your slicer (select both parts, right click and 'merge') - except Door with a GearWheel

Case may be printed without any infill
There are sepparate files for Door and a Nose for No Infill printing - this should be better for transparent filaments but you will need a good cooling
Door also looks nice with Archimidean Chords infill (15%)
GearWheel should have some infill (10-25%). If your kid is small but strong add more infill ;)
