Description
This is a TPU case for the INIU BI-B63 25000mah power bank to hopefully make it more rugged and less slippery. Includes a 1 in wide loop for webbing or other things.
I used this 95A TPU filament: https://www.amazon.com/dp/B07QLRWZWP
Printing tips:
Make sure to dry your TPU filament!
0.2mm layer height
Orient the side with the loop towards the build plate
Paint tree supports on cutouts for the ports and button
Use fuzzy skin to make a nice grippy surface finish
Set fuzzy skin to holes and contours
Use the included modifier to exclude fuzzy skin from the inside of the case
Default fuzzy skin settings in Orcaslicer produces a nice finish
