Last crawled date: 3 years ago

This thing is a remix based on the "ZMR 250 Uni-Spacer with Air-Slots" http://www.thingiverse.com/thing:916537 of "Chr1s" (Jul 8, 2015) which is also a remix of "ZMR UNI-SPACER-v3 by Geekon" http://www.thingiverse.com/thing:915515 of "alexnovik" (Jul 7, 2015).
In my design I have added more holes in the front and rear lateral sides to improve the input of air flow and also I have created several designs changing the high of the uni-spacer and the high of the motors arms. Therefore you can choose among 24 different uni-spacers. It is useful depending on the length of the screws you have to attach the lower parts of the ZMR frame.:
Uni-spacer with high 10 mm for motor arms with sizes 2, 3, 4 and 5 mm.
Uni-spacer with high 11 mm for motor arms with sizes 2, 3, 4 and 5 mm.
Uni-spacer with high 12 mm for motor arms with sizes 2, 3, 4 and 5 mm.
Uni-spacer with high 13 mm for motor arms with sizes 2, 3, 4 and 5 mm.
Uni-spacer with high 14 mm for motor arms with sizes 2, 3, 4 and 5 mm.
Uni-spacer with high 15 mm for motor arms with sizes 2, 3, 4 and 5 mm.
When printing finishes be careful when remove the piece from the hot bed specially if the high of the Uni-spacer is 10 mm or similar because the parts rounding the holes could be damaged due their little thickness.
Regarding the pictures uploaded here, they correspond to the unispacers with high 10, 11 and 12 mm (from left to right) for motor arms with 3 mm of size. They were printed using a 0.8 mm nozle. You will obtain better and more precise results if you use a 0.4 mm nozzle.
