1" to 1.125" Threadless stem shim

thingiverse

Human: Shim that fits 1" steerers by adapting to the more common 1.125" (1 1/8") threadless stems.\nCut it down to match your stem's height or reduce it to its largest percentage below 100% if necessary.\nInstead of leaving it oversized, create a new SLDPRT and extrude it further to remove excess material.\nUsing 1" headset spacers (available as uploaded files) is recommended for steerer adjustment.\nLeaving the shim oversized may cause steering issues due to excessive compression against bearings through the compression ring.\nTested printing has not been performed; use at your own risk.\nThe plastic may not be strong enough to deform and crack, potentially leading to bike steering failure.\nAluminum shims are a safer alternative as they are readily available and inexpensive.
