Low Speed Scanner

The previous clips I designed to fit the mirrors to the polygon mirror mount were a bit pathetic, owing to the fact they had to hold 12 mirrors that weigh 1/4 pound each, spinning at 250 rpm. I've designed some new, bulked up clips.

Consider which way the "grain" is in this sort of printed object. If you print it in a different orientation you can get the filament to go at right angles to the stress-points and provide much improved strength. For example, this looks like it was printed with the lower-edge on the print-bed. Instead, if it was printed in the orientation shown in the picture (i.e., laying sideways) then the "grain direction" would be lengthwise along the piece, and strengthen it greatly. Also, be sure to print this sort of piece "solid 100% infill" to get more material and strength internally. You might also consider increasing the number of "wall" lines to get more of those longitudinal strength-bearing parts - in some pieces I set my wall to 10 or more, so it's effectively all oriented lengthwise along a right-angle bend like this.
