Frog Keychain Accessory (remix)

Instead of a key fob with smooth surfaces I wanted to make something with some unique texture. I could have embossed, raised, or cut in a pattern but I wanted it to be easy to create.

I had seen a CHEP video where the slicer's infill was used to create patterns and make them visible by adjusting the thickness of the top and bottom.

Since the pattern I chose does not interconnect the bottom height was increased and the infill line multiplier was set to 5. That made sure that the infill was sturdy enough to be exposed.

Then the top thickness was set to 0mm to make the infill pattern visible.

Remix Changes

I used Tinkercand and replaced the extended leg with a mirror of the other leg. I also increased height to 4mm.

Print Details

Printer: Creality Ender 3 Pro

Filament: Sunlu, PETG, bright green

Temperatures: 225C / 75C
Nozzle: 0.4mm
Initial layer height: 0.2mm
Layer height: 0.2mm

Wall Thickness: 1.6mm
Top Thickness: 0.0mm (zero mm)
Bottom Thickness: 1.6mm

Infill: 22.5% concentric
Infill line multiplier: 5

Cooling: none
Print Speed(LCD): 100%
Adhesion: 3mm brim + hairspray
Supports: none

Printed on smooth glass using hairspray and a 3mm brim for adhesion.

Manually adjusted cooling from 25 to 30% after the first 2 to 3 layers. This seemed to reduce the amount of fine stringing.

Slowed (via LCD) the print speed to 80% around half-way through.

Post printing clean-up was done with:

Deburring tool - for removing brim remnants and finishing the edges
Hobby knife with a #11 blade - brim removal, deburring, and clean-up
Medium length tapered bead file - for cleaning up places where the knife or deburring tool wouldn't fit

Included File(s)

To Do

Tweak the infill density, multiplier, and other values in order to improve details and eliminate artifacts.
