I built this to suspend a bike from the cieling printed in petg it is more than strong enough.
it is compatible both with 6000 RS bairings using the original desighn of roller and with 6020 RS bairings using my updated desighn
the assemberly is made easy by the resest nuts eliminating the need for an allen key
i printed in petg at 15% infill and it is doing verry well see print file for more information
