fyrtur / kadrilj roller blind - bearing adapter - side mount

thingiverse

Due to non optimal design, after a year of operation, a friction caused damages to the mount. A mini holes are visible on the first picture (marked red) . This wearout causes even more friction. This simple adapter allows you to add a abec 608ZZ bearing to the Fyrtur / Kadrilj roller blinds, on the opposite mount to the motor. -608ZZ bearings are cheap and can be bought in bikes / skates shops for less than 2 Euros Warning - original mounting "mini tube" must be cut off (13mm in height part) (see second picture). Do NOT damage it - You will need it in the next step. In case of damage, you can try to replace this part using "End_Spacer_v7.stl" from https://www.thingiverse.com/thing:5130815/files Printed adapter can be glued or screwed in place of removed tube. Cuted tube must be pushed over the bearing. Use sand paper if necessary. Enjoy even smoother operation of the roller blinds. For the very silent operation - even 3 RPM ! consider modding your motor with a custom firmware prepared by mjuhanne, visit his github: https://github.com/mjuhanne/fyrtur-motor-board
