Parametric Bike Wall Mount

Update: V2.1

Now works with tyres above 45mm thanks to @Googliola ! A proper redesign is needed to clean up the design but this should do for now. 

Update: V2!

The holder is now split into two parts. The wall mount gets screwed to the wall and the bike holder gets slotted on to it. Therefore, if you change your tyres e.g. gravel for road tyres or you have multiple bikes with different tyre sizes you want to store in the same place you can easily swap the holder without unscrewing the holder from the wall. The design is still parametric, even though the wall mount is non parametric so it fits any width bike holder. However, the walls of the holder get pretty thin if you specify a tyre width smaller than 25mm. I would not go any lower and if you go lower use V1 instead. 

Original

This bike wall mount is a parametric 3 part design to fit YOUR tyre width and mount any bike to the wall. The holder is best printed in a material with some flex like PETG  and the insert is intended to be a grippy, softer material that won't damage your tyre or rim like TPU. 

With my 45mm tires on my gravel bike I have no issue easily inserting the tyre or taking it out without any fear of the bike falling down. The design would even work with only 1 insert (although it would be a rather loose fit). 

How to modify the width to fit your tyre

The uploaded STL is for a 45mm gravel bike tire. But the Fusion360 design is fully parametric. You can change the tyre width, size of the screws you use, the height of the holder and adjust the tolerance for the insert if you can't get it to slide in properly (you can cut the insert with a knife or in your slicer and then slide it in piece by piece).

Printing and mounting instructions

I printed the holder from PCTG with a 0.4mm nozzle (4 perimeters and 15% infill) so the holder still has some flex to it. The tyre is friction fitted in and this way the holder has some compliance and can flex without snapping or damaging your tyre or rim. 

For the insert I used 95A TPU (although a bit softer might even be better) with 2 perimeters an 15% infill. 

Be sure to mount the holder with the opening for the TPU slots upwards to avoid the inserts coming out. I suggest to use M4 screws and up to avoid any chance of the holder coming detached from your wall. 

If you do not want to get your wall dirty by your rear wheel print a single layer of white PLA the size of your print bed and stick it to your wall with some weak double sided tape.
