Clamp for keeping smoker bellows closed

thingiverse

This thing is made to be able to close the bellows of a smoker used in beekeeping while the smoker is not in use. The sides of the bellows are made of leather and if the folds are kept open when the device is not used, they might bend outwards when used and the bellows don't work too good if that happens. The opening between is 28mm at the end points and would be 30mm at the base without the curved corners. I printed mine with Ultimaker2 with 33% infill and approx high quality settings, but speed set a little faster. This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/gq6n2q7MOOD EDIT: Old version had few issues and this is an improved version. Old version had an issue with the in-corners, they had too large fillets, this has 2mm so I think it's going to be better. Old version was unnecessarily complex, this has simpler design. I've removed the old version .stl file, but I still left the old picture. Hope this doesn't cause too much confusion.
