These clips are meant to be used along with plexi/lexan panels to enclose your Rigidbot (regular size) for the purposes of preventing drafts from warping delicate parts, and fume extraction.
It's meant to be as small as possible while still allowing the printer its full range of motion. The front and rear panels stick out to allow the table to move past the frame, the top panels allow room for the gantry when it gets to the top of its travel. The spool rack must be moved from the side of the frame to the back, with an extended rod.

Use at your own risk - I am not responsible for any injury or damage, etc.
Parts needed:
-lexan panels, 18x24" is ideal to minimize cutting
-M3 x 10mm screws, qty 4
-CA glue (superglue)
-8mm x 47cm spool rod
-means of cutting lexan (prefer dremel and jigsaw)
-drill and 3mm bit
Read through all these steps before starting! This is just a general guide. I know these will be long prints, so set them for low quality. On mine I ended up printing everything shorter and taping the seams.

1. Panels are to be cut as shown on the drawing. I suggest cutting them as you go and confirming fitment along the way. Cut two of each panel size except the "top horizontal" panel, which only needs to be cut once.
2. Use the "lexan side upper supports" and "lexan side lower supports" to attach the left and right lexan panels. Do not glue the panels to the lower supports, doing so would make it difficult to remove the enclosure. Line up the upper supports, mark and drill the panel, then screw the panel to the upper supports.
3. Glue the "front and rear panel sliders - bottom" to the four bottom corners of the left and right lexan panels. The larger slots should face inward and that's what the front and rear panels will slide into.
4. Glue the "front and rear panel sliders - top" above the bottom sliders from step 3
5. Glue the "front and rear top cover mounts" to the upper edges of the left and right panels, on the front and back, then glue the "front and rear (top)" panels in place.
6. Set the "diagonal panel lower mounts" on the top of the frame on the front and rear side. Glue them to the "front and rear (top)" lexan panel.
7. Glue the "top diagonal" panels into the mounts from step 6.
8. Glue the "top center cover angled clips" to the "top horizontal" panel, leaving a gap in the middle for the filament to be passed through. Then glue this part onto the top sides of the "top diagonal" panels.
9. Trace and cut the trapezoid shape for the side panels needed to close in the top part. I was never able to draw this and have it work out, so I am saying to trace it instead. Leave a bit of a gap for the clips.
10. Glue the "top center cover 90deg clips) to the top edges of the trapezoid panels, and the "top diagonal cover 90deg clips" to the diagonal parts. Then glue this to the sides of the top diagonal and top horizontal panels.
11. Figure out which panel you want the fume extraction fan to be placed, trace it and cut it out. Screw the fan to the plexi from the inside, then find and print an adapter to connect whatever size duct you are using, to the fan.
12. Move the posts for the spool rack from the side to the back of the frame, and reinstall with the longer rod.
    If you need to remove the enclosure, simply undo the 4 screws on the side panels and the whole shebang should lift off.
