I needed someway to have some space in my shed.  Storing the bikes vertically on their back tire against the wall saves lots of space so I designed these wall hooks to hold the front tire.  Just screw them into the wall, in my case a 2x4 at the right height and regain some floor space.  I print these with 5 perimeters and 25% infill as they need to be pretty mechanically robust. I would do PETG if I had any on hand the examples are in PLA Professional.
