Bike Stand

thingiverse

I grew frustrated with leaning my bikes against walls so came up with this bike stand, inspired by display stands found at local bike shops. I printed the 95mm size for my Trek 7.2Fx and the 65 for my Domane 4.3; both are remarkably sturdy. To determine the right size you need, place your bike upright against a wall and gently lean it to one side. Measure from the ground up to the end of your crank arm. Before printing, I recommend printing the small crank tester first – this part is as large as the full stand, and lets you see if your crank will fit perfectly in the stand (and can easily be resized to suit your needs). This design is based on a crank with 15mm depth and 35mm width; my hybrid has a Shimano M191 crank, and I've successfully tested it with a Shimano 105 crank from my Domane. Therefore, it should work for most bikes. When printing the stand, please remember that it's meant to be at an angle when in use but flat while printed – which helps save plastic – so don't lay the entire thing flat on the ground. Instead, only let the ends of its feet touch the ground when you put your bike on it. My maximum load test was conducted with my hybrid weighing approximately 30lbs; I've had it easily hold my Domane, which weighs about 19lbs, without any problems. It also stopped one of my bikes from falling after I bumped into it. However, I accept no liability for any damage that may occur while using this stand. Just because it was able to hold both of my bikes at the right angle doesn't mean it'll work with yours. Print Settings: Printer Brand: MakerBot Print Method: MakerBot Replicator 2 Rafts Used: Yes Supports Required: No Resolution Achieved: 0.2mm Infused Density Achieved: 10% Infill I printed my stand using the Makerware software, which gave me 10% infill, 2 shells, and 230° temperature; extrusion was 90mm/s. The result was strong yet still quite sturdy – and by adding 20% more material or 2-3 additional layers, it becomes even stronger. But please keep in mind that you can also print without supports – which means the underside might look slightly messy but it'll still do its job perfectly well! To assemble, slide the stand over your bike's crank arm. Adjust the stand to get your crank near vertical orientation with the side facing downwards; after leaning the bike against the stand hold it in place for a moment to test that everything works properly – release the tension only when confident. You might want to avoid making stands too long, or bikes will lean away from their stands rather than relying on them – which is something I encountered firsthand with my setup. On the flip side if you create one too short it could mean that your bike ends up leaning beyond its limits; remember to print the stand so that it remains upright in usage while still staying relatively flat while not being used. Determine Size Needed: Measure from the ground upwards, then note where your crank arm begins and ends - now all you have to do is find out which size will hold both your bikes. To find out how tall a print needs be, take your bike upright place against it with only gentle push for support measure lengthwise, up the sides to find this exact area's length, once done compare these two results to decide whether or not printing in either size will allow full success - but just do a test piece before actually committing to that size by measuring along same spot until satisfied that there won't be problems with dimensions later on so then re-size fit into your if still struggling print crank stand again at different settings, try various parameters until finding one that'll get right measurement needed for the rest of project once these changes finalized printing complete, it may also depend on printer capabilities – you will know what setting works.
