Powerful small belt buckle - snap clicp 3D print model

Hi, this is a set of mini buckles / snap-on clips that you can use for many things. The design is optimized for 0.4 nozzle. In the video below I print it at layer 0.2 and 40% infill but I suggest to print it at full infill. There are two version, one for 4mm cord and one for 10mm flat belt.

For now, it is tested for weights up to 30lb (13kg) without any problems as you can see in the video below.

Suggest print it:

• print as you see in image
• layer 0.2 or 0.1
• 2 wall / 0.8mm
• 4 top/bottom / 1mm
• 50% or full infill
• support everywhere
• Use ABS / HIPS (PETG, I think yes but I not tested)
