<p>This is an update version of my OAT controller enclosure. The original can be found here:</p><p><a href="https://www.prusaprinters.org/prints/137723-openastrotracker-controller-enclosure">https://www.prusaprinters.org/prints/137723-openastrotracker-controller-enclosure</a></p><p>This version has added ventilation holes for better airflow to the stepper drivers, an additional GX12 hole so up to 6 can be mounted now, blanking plates to plug up any unused mounting holes and a reworked antenna retainer for the GPS. There is also insets on the lower case for 12x12mm square rubber feet.</p><p>As with the original, all can be printed without supports, and is intended to have M3 brass heat-set inserts used in all the board mounting points and the 4 points in the lower case where the top is screwed down to.</p><p>The supplied .gcode files are all for prusament PETG, .2 layers and 20% infill.</p><p>If you slice your own from the STLs, 20% infill is plenty.</p><p>Also supplied - png files for all the labels, and a DXF for the red acetate filters.&nbsp;</p><p>If using filters the .2mm thick acetate I used required 3 layers to a decent red colour. If you do the same, use the longer button pushers as the acetate will push the LCD away from the case. If your filters are a different thickness or you need more or less layers - remix the pushers accordingly.</p><p>&nbsp;</p>
