Tensioner holder dimensions depending on idler tensioner sizes. Idler tensioners with different leadscrew diameters. Idler tensioners with different wall thickness. Idler tensioners with different stroke lengths. For example, the space for the pulley or the tensioner width are smaller for case A than case B, as the figure shows that sep_m3 < sep_m4 and tens_w_m3 < tens_w_m4. The size of the idler tensioner is smaller when it contains an idler pulley using a M3 bolt (A), than when using a M4 bolt (B). Two filter holders for different filter sizes and linear guides.Įxample of an idler pulley made out of a bearing and some washers.Ĭomparing two idler tensioners made out of different components. Two brackets for different stepper motor sizes. (B) Side view of the extended belt tensioner.ģD printing orientation of the four printable models to avoid supports. (A) Side view of the retracted belt tensioner. The leadscrew tightens or loosens the idler tensioner (orange). The two printable parts are drawn in colors: tensioner holder (blue) and idler tensioner (orange).
(B) Exploded view of the filter holder assembly to a linear guide.
(A) Drawing showing the filter holder parts. The bracket and the stepper motor are partially transparent to show the internal parts. Printable parts are highlighted with colors: motor bracket (green), filter holder (yellow), belt tensioner (blue and orange).
