The 35mm file worked with these spindles from Amazon:http://www.amazon.com/gp/product/B002BW1DH4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

We recommend printing the pedal spindle facing side down (the side with approx 1.5 mm of space), with a raft and no supports.

Pedals shown are the 35 mm file at 40+ percent infill, 50 mm/s printed via 3DPrinterOS on the Replicator 2. Use at your own risk!
