This is a remix of @BikeCyclist bag clip.
I printed this in PLA with a 0.4 nozzle at 0.30 mm Draft with 5% infill.
The lengths here are the "clamping" length the clips can hold, not the total length of the clip.
I've added the .f3d too, so you can make whatever length of a clip you want. The length on the f3d model is always 20mm longer than the capacity of the clip.
Feel free to modify this model in any way and for any purpose you want.
I've made an updated version with help from @Tvorim3D .
It has a longer and thinner latch arm and a chamfered edge on the non-latch side to make the locking smoother and less prone to breaking
The author remixed this model.
I didn't like the joint on the model. It was too loose. So I removed it and just have a compliant mechanism instead.
