Bike pump holder ⌀27mm

thingiverse

A remix of Tiefflieger's nice bike pump holder. This was designed for my JetBlack 27mm diameter pump, the stock holder had some very very poor quality screw holes, almost designed for you to lose both pump and holder if you didn't have a bottle cage above it. This print is designed with a 26.5mm internal clamp so that it grips firmly, even without the strap on. The original STL part was imported into SketchUp, scaled up along the X and Y axes, then the screw holes were scaled down along the X axis so that they retain their original shape. I printed it vertically so that it is more resistant. I used a tree support for the top clamp but none on screw and strap holes as they are not necessary and are hidden anyway, I used support blockers to achieve that. I printed in 0.1mm with 5 walls and 30% infill, it is equivalent to a higher infill but more resistant and elastic where the part is narrower, giving it essentially a 100% layered infill on those areas.
