Adimlab X-Tensioner Improved Remix
Description
This is a remix of the original FB Group Adimlab Gantry printer X-axis belt tensioner. This improved version thickens the base and top and adds a second triangular brace on each side for improved stiffness. The pulley housing area is lowered about .5 mm to restore the original position of the OEM pulley. The idler pulley is also remixed to account for slightly larger screw heads and it has been thickened for improved strength. HARDWARE: Use the OEM hardware that came with the printer to attach the tensioner to the printer. Use at least a 3mm x 35 screw to go through the pulley. You could also put a 3mm nut on the other side of the pulley to keep the screw from spinning. Use a 3mm nut in the knob. Don't use a nylock nut in the knob as it will put too much tension on the screw and it will just spin. 04/25/2020 UPDATE: Note the knob is different than the picture. Also updated the info on the hardware. 02/16/2020 UPDATE: When I printed this the front brace in the slot didn't work out so I have removed it. 12/29/2019 UPDATE: Corrected an issue with the v3 pulley. It should slide all the way back to the screw opening now. 9/14/2019 UPDATE: Version 3. Updated the model further including one with Adimlab logo and one without the logo. The pulley has proven to be weak so it is now thickened a bit. Probably best to print the pulley in PETG or ABS for strength, but this thickened part should hold up with PLA.
