Over the summer i bought rollers for riding my bike indoors. It was missing a part, the seller disappeared, and the manufacturer no longer has the parts.Luckily this part was one of 6 so I had a piece to measure out. Used digital calipers to build it up in Sketchup Make, and printed at a local 3DHubs printer. Hoping to get a MP Maker Select but this cost me like $5 to have printed so I cannot complain at all. Installed on the roller today and it fits like a glove. Printed in black ABSIn case you were wondering, the purpose of the part is to properly hold a nut inside the frame so a leg can be threaded onto it. It also functions a sort of a foot when the roller frame is folded in half for storage.Here are a few pictures, printed on the left, original on the righthttp://imgur.com/a/0f7SuHere is the STL file in the rare chance anyone else needs one of thesehttp://www.thingiverse.com/thing:1905196All of the square recesses in it were just to roughly match the original to save on material. In hindsight I should have left it flat as this created overhang problems for the printer. http://ift.tt/2gboofG
