Multi-size cup holder for a bike

thingiverse

This is my remix of Bike Coffee Holder by mr2quick. I modified it to hold any cup size, from small paper ones from a coffee machine (about 60mm in diameter) to big ones (up to about 82mm in diameter). If this range isn't enough for you, simply modify the attached SCAD file. I tested the internal ring to be strong enough to hold the small cup and still flexible enough not to break when stretched with a bigger cup. Another modification I made was adding a small cutout in the clamp for more flexibility during installation. The original version broke on me, so I fixed that issue. For installation, apply one wrap of masking tape on the handlebar first to prevent slipping. Printing: I recommend setting the line width to 0.5mm because the inner ring is exactly 2mm wide. I also used brim since the part came loose twice.
