Anycubic i3 Mega Y belt tensioner for up to 9mm belts

thingiverse

I built this thing for my own use, but if it's been helpful to you, please consider making a donation via http://bit.ly/Bart3d or the TIP DESIGNER button. Made this Y belt tensioner for the i3 Mega. It will fit up to 9mm wide GT2 belts. I used 9mm Gates belts. The belt path is perfectly aligned with the pulley and idler. Parts needed: - Note that the stock belt is probably too short, so you'll need a new belt to use this tensioner. - 3 M4x16mm bolts - 1 M4x24 to 30mm bolt - 4 M4 hex nuts - 2 M3x10mm bolts The M3 bolts don't thread into anything; they're only used to secure the belt. Wrap the belt around the bolt and then slide it into the slots. Cut any excess belts off, especially on the front side. There's minimal clearance with the idler when the bed is at max Y.
