Maker Coin

Summary

The task was to create a maker coin with a specific set of constraints:

• All coins must be made from an initial revolve resulting in a coin that is 6cm in diameter and 1.25cm in thickness.
• Must not require ANY supports, (no supports).
• Should be gear-esque in nature.
• NO moving parts, (no gyroscopes, fidget spinners, etc.)
• Must slope downwards towards the center in some fashion.

Overview and Background

I started by researching Maker Coins and finding one with a gear shape that I liked. https://www.thingiverse.com/thing:3377304

I then started designing the logo that would be placed in the center of the coin. I knew I wanted the design to be some sort of abstraction of my initials (PD). Initially I created a design with the initials side by side, but I thought it looked too simple.

I redesigned the logo and came up with a design where the P and D were combined into one symbol.

This design was going to be mirrored  to create a circle, but I decided to have the design on only one side so another design could be added on the other.

Like my inspiration, the coin was initially going to have 7 gear teeth, but I added one more to make the coin more symmetrical.

I wanted the coin to curve down from the outside and then have the logo angle upward on each side.

I tried modeling the coin as one shape, but I couldn't figure out a way to create the shape I wanted for the logo without damaging the base of the coin. To solve this, I created the logo and base as separate models and combined them in an assembly. This ended up being an advantage, since the coin had to physically be put together in 2 parts which allowed the logo and base to have different colors, giving the coin a unique look.

Initially, the cuts in the logo on the coin did not go all the way through, but I changed it so that it did since it looked better to me.

The coin was missing something to really wrap the design together, so I added a circular cut with symmetrical circles on the inside to add more intrigue to the coin. I also added filets to all the edges in the model.

After

My initial idea was to hot glue the logo onto the coin, but I instead added a hole in the base and extended the logo so they could fit into each other, removing the hassle of a hot glue gun.

Assembly Instructions

1. Download and print one Desanges_makercoin logo.3MF and one Desanges_Makercoin Base.3MF. (Tip: As seen below, try printing the logo and base as two different colors for a unique look.)

2. Insert the center logo piece into the slot in the base through the bottom.

3. Push the logo into the base.
