Chitu E1 Dryer - Hygrometer / Thermometer mount - Horizontal

Remix of the system  to add a cheap rectangular hygro- / thermo-meter from (e.g.) aliexpress to the Chitu E1 dryer box instead of the paper indicator strips that came with the boxes.

Didn't like how the original version was sideways, or how you had to disassemble the hygrometer to mount the internals into the holder.  I also ran into an issue with it during a print since it was contacting on one of the spool edges from the front, that seems to have caused a spool to go wonky on the rollers during an overnight print and get stuck, and the printer then yanked the whole box off the dryer base before realizing the filament is tangled and pausing the print.  

This version will not require disassembly, just shove the hygrometer into the hole in its original casing.  It will be held horizontally between the spools sides.  It comfortably fits between all the 1kg spools I tried, but 500g spools were too narrow and the sides rubbed against the hygrometer, so probably best place those on the other lane of the dryer box.  Anything narrower is right out, obviously.

I designed the hole such that the overhang should have just x and y bridges, instead of needing to print on air; so supports should not be required, but YMMV depending on how your slicer and printer are set up.  If you do run into issues, you can probably just flip it upside down so the small tab designed to interface with the clip in the box is below the print surface and doesn't get printed... it'll probably do just fine without it with just a friction fit, but I've left the tab there since my printer / slicer didn't have issues with the bridging style overhangs.
