I made these to clamp a bicycle pump to my motorcycle for MS rides which I assist on. You will need to print two of these and they should be printed laying on their side such that, when viewed from above, they look like the letter C. This orients the plastic filament such that the layers are not stressed when the clamps are used. This fits my old (bought in 2005) Joe Blow pump but also a newer one I bought around 2016. I used #10 coarse-thread wood screws which were 1 inch long to affix these to the top of a Craftsman storage box I had on the back of the motorcycle. I used them this Spring to do two MS rides and this mounting was the best I've had in 19 years of doing MS rides.
