A handy coin holder for your car, pocket or bag. The coin holder is designed to hold the £1 (both old and new designs), 50p, 20p and 10p UK sterling coins that are currently in circulation.
1) Place a spring into each of the coin silos within the 'Base' part.
2) Carefully place the appropriate 'Plunger' onto each of the springs (each 'Plunger' is designed to fit exactly within a specific coin silo).
3) Apply glue to the bottom of the 'Top' part (the bottom is the side that is not flat).
4) Taking care not to displace the 'Plungers' carefully glue the 'Top' and 'Base' parts together. You may wish to clamp the two parts together in order to ensure a good bond.
5) The coin holder is now assembled.
I have now added an alternative 'Base (Extended)' part that has more capacity and that can be used in place of the 'Base' part. I keep an extended base version of the coin holder in my drawer at work, to use in vending machines etc.
The design has been amended so that the coin holder can accommodate the new design £1 coin that entered circulation in 2017.
Materials and methods
-Filament of your choosing (The example shown in the photographs I have provided is printed in ColorFabb PLA/PHA 'Sky Blue' filament).
-4 Springs . As a guide the specifications of the springs I use within the design are as follows:
Uncompressed Spring Length (mm) - 23
Wire Thickness (mm) - 1
Inside Diameter (mm) - 17
Outside Diameter - (mm) - 19
PRESSURE At 50% Compression (Grams) - 350
When creating an extended base version of the coin holder I use 8 such springs and superglue them together in pairs to create 4 longer springs. I find Loctite 'Power Easy Gel' to be very effective for gluing the springs as it is less runny that most glues and it stays on the springs long enough to create a strong bond.
Issues are used to track todos, bugs or requests. To get started, you could create an issue.
I have updated the Base, Base 'Extended', Top, and 1 Pound Plunger designs so that the coin holder can now accommodate the new design £1 coin that entered circulation in 2017.
I have now added an alternative 'Base Extended' part that has more capacity and that can be used in place of the 'Base' part. I keep an extended base version of the coin holder in my drawer at work, to use in vending machines etc.
