thingiverse

Human: Just a Remix of the Tensioners designed for my Cr-10, as requested by user TallDonkey on the original Y Axis Tensioner page. Update of June 29, 2019 MAJOR UPDATE! Y Tensioner for Ender 3 Mk7 Version Upgraded the guide system and simplified all the models Unified the screws dimensions with my other tensioner versions Modified the minimum belt tensioning position for short belts Increased the tolerances compared to previous models Added a New Shaped Knob more fancy than the previous version Printing Tips: Print Body in Vertical better with supports Print Screw Horizontally lying on the flat face Print Knob in Vertical No supports Required Hardware Requirement: For the F688Z Bearings Version OEM: 1 Screw M4x20 Button Head Need use adapter Or 1 Screw M8x20 Button Head 2 Bearings F688Z 2 Screw M4x8 Button Head 2 T-Nut M4 For the F624Z Bearings Version: 1 Screw M4x20 Button Head 2 Bearings F624Z 2 Screw M4x8 Button Head 2 T-Nut M4 For the GT2 Version: 1 GT2 Pulley 20T 1 Screw M3/M4/M5 x20 according the Pulley bearings 2 Screw M4x12 Button Head 2 T-Nut M4 Fixing system: - 2 screws M4x8 - 2 t-nut M4 The models are designed for the material stated below. Note: I didn't print personally this version but fittings and tolerances are the same for all my models so I am sure they fit together correctly! If you cannot fit the pieces after the print you are doing something wrong! (Sorry guys but I am tired of comments from people who are unable to print and blame the models...) Update of July 22, 2019 Small modification to the body model in order to have a smooth transition from the tensioner body to the frame. Furthermore added the body version for GT2 pulleys for this kind of pulleys the screw will sit 2 mm lower than the OEM version due to GT2/OEM sprockets pitch diameter differences. Hope you enjoy it.
