BMX Foot pegs

thingiverse

My son wanted foot pegs for his BMX. The correct diameter to be fitted on the wheel axle wasn't avalaible at the shop. So i designed it. And printed it with polycarbonate (color is flashy....) There are 2 sizes: 13mm center hole to fit the rear axle. 8.9mm center hole to fit the front axle. I didn't design any threads, as the axle threads are very very fine, so i'm sure it wouldn't have printed correctly. So you have to "force" the peg into the axle, thus creating the thread like with a tap.(put some grease to help) You need 2 of each obviously. I did 3 processes in Simplify: -For the first 20mm in height : infill at 100% and 10 perimeters , to create a very strong shell around the axle of the Wheel) -Then from 20 to 100 mm, 70% infill,10 perimeters -finally above 100mm, for the nut, 100% infill,10 perimeters It seems to be strong as i can jump on the pegs (63 kg) No supports while printing but a good raft (2 layers) with the polycarbonate to avoid systematic warping. Print Settings Printer: Felix Pro 1 Rafts: Yes Supports: No Resolution: 0.2 Infill: 100% most of the volume Notes: Create several processes in Simplify3D to change the infill according to the height of the peg
