Important Printing Information

This is a digital 3D-printable design.

Final print quality, dimensional accuracy, fit, stability, and strength may vary depending on printer, nozzle, filament, calibration, layer height, wall settings, infill, top and bottom layers, supports where required, orientation, bed adhesion, colour-change setup, and slicer profile.

Always inspect the sliced preview carefully before printing.

Pay particular attention to:

• Coin slot dimensions

• Pen-holder opening

• Character attachment points

• Arms and legs

• Thin decorative details

• Base flatness

• Layer adhesion

• Any areas carrying the weight of coins or writing tools

• Small protruding features

Normal FDM characteristics such as visible layer lines, seams, slight dimensional variation, and minor surface or colour differences should be expected.

Sandstorm 3D Designs is not responsible for failed prints, wasted filament, adhesion failures, incorrect slicer settings, dimensional variation, colour-change problems, printer malfunctions, weak layer bonding, broken components, improper assembly, or other printing-related losses.

Files are supplied as-is, and the user is responsible for selecting suitable materials, printer settings, assembly methods, and final use.

Piggy Bank & Coin Use

The Penny Pop Pal is designed to hold ordinary loose coins inserted through the coin slot.

Coin sizes and thicknesses vary between countries and denominations, so users should confirm that the coins they intend to use fit comfortably through the printed opening.

Do not force oversized coins or other objects through the slot.

Overfilling the bank may increase the weight of the finished product and could place additional stress on the base, body, or printed connections.

For safe use:

• Add coins gradually.

• Keep the bank on a stable surface.

• Do not shake or throw the filled bank.

• Avoid overfilling.

• Inspect for cracking or layer separation as weight increases.

• Stop using the bank if the body or base begins to deform or crack.

Sandstorm 3D Designs does not provide a guaranteed maximum coin weight because finished strength depends on filament, print settings, wall count, infill, layer adhesion, and printer calibration.

Coin & Choking Safety

Coins present a serious choking hazard for young children.

The Penny Pop Pal should not be treated as a toy, especially when it contains coins or other small objects.

Keep loose coins, broken printed pieces, and any removable components away from young children and pets.

For households with young children:

Not recommended for children under 5 years of age without direct adult supervision.

Never allow a young child to play unsupervised with loose coins or small pieces from the finished print.

Pen & Pencil Holder Use

The pen-holder portion is intended for lightweight everyday writing tools such as compatible:

• Pens

• Pencils

• Markers

• Similar lightweight desk accessories

Do not overload the holder with heavy tools, scissors, metal instruments, knives, or other objects that could make the model unstable.

Writing tools may have sharp or pointed ends.

When used around children:

• Keep pointed pens and pencils out of reach when appropriate.

• Do not allow children to run or play while carrying the holder.

• Position writing tools so they do not create an obvious puncture hazard.

• Do not use the holder for knives, blades, needles, hobby tools, or other hazardous objects.

Stability & Desk Safety

Because the Penny Pop Pal may contain both coins and writing tools, its balance can change depending on how it is loaded.

Always place the finished model on a flat, stable surface.

Before use:

• Make sure the base sits flat.

• Check that the model does not rock or lean.

• Distribute writing tools reasonably evenly.

• Avoid placing excessively tall or heavy objects in the pen holder.

• Keep away from table or shelf edges.

• Do not place where it can easily be knocked onto someone.

A heavily loaded piggy bank should not be placed on a high shelf or unstable surface where a fall could cause injury or property damage.

Filament & Durability

PLA is generally suitable for normal indoor decorative and desk use.

However, PLA may soften or deform when exposed to excessive heat, direct sunlight, or hot vehicles.

PETG or another suitable filament may provide additional toughness depending on the printer and intended environment.

Whatever material is selected:

• Ensure good layer adhesion.

• Avoid using prints with cracks or under-extrusion.

• Inspect thin character details carefully.

• Keep away from excessive heat.

• Keep away from open flame.

• Replace the product if structural damage develops.

No filament makes a 3D-printed product unbreakable.

Cleaning & Care

For normal care:

• Remove coins, pens, and other contents before cleaning where practical.

• Wipe gently with a soft dry or slightly damp cloth.

• Use mild soap only when necessary.

• Avoid harsh solvents or aggressive cleaning chemicals unless compatible with the selected filament.

• Dry thoroughly before returning coins or writing tools.

• Do not place in a dishwasher.

• Do not expose to boiling water or high-temperature cleaning.

Safety & Intended Use

Penny Pop Pal is intended as a decorative desk accessory, coin bank, and lightweight writing-tool holder.

It is not intended as:

• A toy

• A teething product

• A food-contact container

• A climbing aid

• A structural product

• Safety equipment

• A container for hazardous materials

Inspect the finished print before use and periodically afterwards.

Discontinue use if you notice:

• Cracking

• Sharp broken edges

• Layer separation

• Warping

• Loose limbs or decorative pieces

• Damage around the coin slot

• Loss of stability

Broken 3D-printed pieces may have sharp edges and should be discarded or repaired appropriately before continued use.
