Kossel Delta Printer Enclosure

https://drive.google.com/file/d/1fa5pm2XZH_6U6HD54T5FuTp0mGkehUUp/view?usp=drivesdk This enclosure builds on to the existing frame. I designed it so you could have full access to the print from any angle. Some things may have to be modified for different configurations/sizes. Step files provided so you can alter the cad as necessary. I used clear polycarbonate 1/4" sheet for the doors and vertical edges, cut with a jigsaw and finished with a belt sander. That was just a tad frustrating because jigsaw will walk and I suck at that. I put in about 15° miter on the center seams. PC is pretty expensive and 1/4" is overkill. 1/8" would have sufficed. PC is much better than acrylic though, as it wont crack easily. Also I use springs to hold all doors shut, but obviously you could install magnets or latches or whatever. Once constructed, this structure will expose how misaligned your towers are. I recommend an auto calibration. A side effect I have noticed from stiffening up the structure is that ghosting is greatly reduced =D ... I am now considering installing torsional tie rods to the top half. Also wanted to see the temp in chamber so I set the firmware to think there is another hotend and plugged in a thermister to those pins on the motherboard, routed it up with the hotend wires so it reads the temperature just above the hotend and always displays it on screen. I only print ABS so there is no need for "RAMP_1.4_EFB" (extruder, fan, bed). It's set to EEB. Also I removed the part cooling fan from the hot end so there is less mass moving around. I will throw the config file up. version 1.1.x bugfix With bed set to 95°C, the chamber stabilizes to about 45-50°C.

Also, I designed it so the vertical members (doors and edges) are 24". The doors are 6" wide and edges are about 1.5", but I just measured them last and cut them to fit (1.43"). so a 24" x 48" panel/sheet works.
