This thing is a remix of https://www.thingiverse.com/thing:3835593 and https://www.thingiverse.com/thing:3909930. The bucke is improved and much smaller. I had some problem that the buckle of thing 3909930 opened for its own under heavy load.
The 20mm belt is included as a stl file in addition. This stl is much smaller than the belt from thing 3835593 and will therefore be calculated much quicker in cura. If you want a different width, I recommend to scale it by modifying the Z-factor inside your slicer program.
The 20 mm belt can be scaled as follows:
Z-factor -> resulting width
1.25 -> 25mm
1.50 -> 30mm
1.75 -> 35mm
2.00 -> 40mm
2.25 -> 45mm
0.2 mm Layer - 0.4 mm Nozzle
Glueing the thing
For a quick test you do not need to glue the belt onto the buckle, but if you want to use ist frequently it becomes much more convenient. See the gallery images for more ...
