I created a 3D printable badge which uses three layers to sandwich Tufty 2040. The three sections are held together using M2 18mm machine screws.
To power the badge, I used a 1000mAh LiPo battery which fits neatly inside the case. Note that Tufty 2040 has no charging circuit, so batteries / cells need to be charged externally.
The badge was printed using Overture Neon Green silk PLA on an Ender 2 Pro.
I printed using the following settings
bed_temperature = 60
bottom_fill_pattern = monotonic
top_fill_pattern = concentric
bottom_solid_layers = 5
fan_speed = 100
0.16 quality
0.4 nozzle
infill = 25%
first_layer = 210 Celsius
other_layers = 205 Celsius
travel_speed = 100
perimeter_speed = 40
solid_infill_speed = 40
top_solid_infill_speed = 30
first_layer_speed = 20
infill_speed = 40
