Training wheel bracket

thingiverse

I took my older daughter's bike to have its original training wheels refitted on a Raleigh bicycle for my younger daughter. Unfortunately, one of the plastic brackets was broken - the part responsible for keeping the training wheels from damaging the bike. My immediate thought was: Where can I possibly find these parts? However, it didn't take long for me to come up with a plan - I have a 3D printer at my disposal! To get the job done correctly, I had to make sure I got all the dimensions just right. The prints came out faster when they were printed on their side, but that wasn't ideal because I wanted the part where metal is used inside it not straining against anything. Print Settings: Printer Brand: Printrbot Printer: Simple Black Rafts: No Supports: No Infill: 100% It's worth noting that printing at 100% infill can help the parts turn out more sturdy, but you have the option to print it on its side if speed is a concern. That's exactly what I chose not to do - instead opting for prints where the weakest dimension will be taking the strain caused by the metal. To design this bracket, I used a pair of calipers and Openscad - and let me tell you, it's a powerful tool that any maker would appreciate using. I relied heavily on variables while designing so anyone with a similar part could modify it for their needs.
