Summary

JD SMART KEYCHAIN v1.0
• Small size: 63x30x13mm
• Very fast print: Less than 1 hour (the print shown was done in 28 minutes)
• Phone stand (tested with a large iPhone 8 Plus)
• Cart coin (ø23.24 x 2.3mm; compatible with 1 Euro and Danish 10 kroner)

I wanted a keychain with multiple purposes, and so I made this combined shopping cart coin and phone stand.

There are two files for the coin; one with my Gentry logo on it and one BLANK, on which you can put your own name, logo etc.

Rafts:                     

Yes

Supports: 

No

Resolution:                     

0.2

Infill: 

20%

Notes:                    

Raft is only needed for the keychain par, as the flanges warp relatively easy. To ensure that you avoid warping, just print the keychain on a raft with at least 5mm extra margin.

The 20% infill is due to the need for increased tensile strength, as this is a thing that will live in your pockets and probably get bent when you tie your shoes etc.
