6 month update: still going strong! Super durable and staying clean.
An actual, functioning bifold wallet! I've been using one for months with no damage. I like the clear to see whether or not I have money, but an opaque color could be more discreet.
Printed in Ninjaflex with the Flexion Extruder
We had to add a connector between the two card holder slots to get a smooth vertical wall. Otherwise it bends too much under the nozzle pressure. You can cut that off with scissors pretty easily. Also, a single nozzle width would have been good, but the wall is too tall for that. This has two nozzle widths (0.8mm) and everything holds together really well.
This is a little more difficult to print, so we highly recommend getting a Flexion Extruder and dialing in your settings before you try.
