Anycubic I3 Mega belt tensioner

thingiverse

Because the tiewraps didnt work, i designed a belt tensioner for the Anycubic I3 Mega. Just 2 parts, roughly 19 min to print on my Anycubic and just 2 m3 bolts and 2 self securing nuts (or 4 nuts) are needed. I used m3 x 25mm bolts because it is easier to tension the belt if they are a little longer than needed. But m3 x 20/16 will do the job too. Edit 23-1-2018: i re-designed it a bit (5 mm longer on both sides and 1 mm thicker, Use also self securing nuts, locktite or 2x2 nuts because they will getting loose if you don't. If you really want to be sure, use tiewraps on the ends to squeeze the teeth together, because heated beds can make the pla bend, but i will test the new design soon without tiewraps.
