I ordered some custom Voile straps as part of a product I'm selling. I should have bought some keepers too - but I didn't! Here's a 3D printable version. I'm printing it in the “TPU for AMS” from Bambu Lab, which is listed as having a Shore hardness of 68D.
These are designed for the 0.75" wide straps, not the 1" wide ones.
I print these with thick lines and a tall layer height. Feel free to peep the .3mf if you'd like to follow the same settings.
The author marked this model as their own original creation.
