A customisable version of the enclosure for the Duet electronics for the reprap Ormerod printer.
Overall depth for extra room
Extra mounts to allow better horizontal positioning
PC board can be separate from main mounts to allow enclosure mounting with PCB in place
Base can be solid or hollow (using original acrylic plate)
Wall near cables can be cut out or filled in
Cut out for aux 5v connector
Optional extra are reset / erase pins and guides to allow these two on board buttons to be easily pressed without taking cover off
The supplied stl is for the version as illustrated. To customise just edit in Openscad the entries near the top of the file and export a new stl.
The DuetEncMeasure scad is not needed but allows for measurements and comparisons against the reprap original Duet enclosure. This needs the reprap Duet-enclosure.stl file.
As this one has the separate PCB mounts to the rail mounts it is not a straight replacement if using the acrylic for front and back.
1) Saw of the external rail mount hole tab on the acrylic, retain as extra spacer.
2) Trim off bottom of acrylic (with logo), about 3mm. This is to allow it to clear the new rail mount holes which are just below the PCB holes.
3) Screw in PCB to new mounts and into the acrylic. This needs slightly longer screws as the PCB is stood off from the base of the enclosure. I used 12mm. The mount holes are made slightly smaller than clearance so that can be tapped if using a completely solid base. So either tap or clear out a bit to use with acrylic.
4) Put on the 3 T nuts. I used the existing screws for these but countersunk would be better for internal ones. Use the acrylic from 1) as an extra spacer on the external tab and extra spacers on the internal ones to bring up to the level of the acrylic. FOr the right hand internal chose the hole to allow for extra postioning freedom. The one nearest the centre still makes for a rigid mount and allows the enclosure to be moved well away from fan.
The optional reset pins and guides are designed to be used with the existing acrylic cover where there are already holes in the right place. The guides are intended to be super-glued onto the inside of the acrylic and make sure the pins locate over the on-board switches. The gudes need to be cut to length to suit the depth of the case. The height of the pins can be adjusted in the SCAD for different size cases as it is good to have the conical tip to make clicking the button positive.The reset guide can extend most of the way to the board. The erase guide needs to be much shorter else it will clash with the ethernet connector when trying to put the lid in place.
