I love my original Kossel Delta Printer, But i hate that it only has a small print bed. So this project is to enlarge my Kossel to the full size 220 print bed. I am using https://www.thingiverse.com/thing:154832 as part of my rebuild of my delta. please give credit to https://www.thingiverse.com/Crashoverride for his help in designing this upgraded Delta. I used #8 3/4 Self Drilling Screws to mount the 3/4 inch Aluminum square tube to the printed ends. I just did my final Calculations on this Upgrade. This new design can print on a 225mmx844mm area or 9 1/16"x33 1/4" area. Final Print size is 230x509.5 or a max of 230x527.5 6/5/2017: Update. I had some problems getting the Extruder base to sit level when i was doing the Dry Run process. so I've updated the RODS to 300mm from Center to Center. With that update I was able to get a print surface of 250x475. SIDE NOTE "I'm not trying to take credit for all of the stl files, yes I have modified them to work on my design. and yes you may have seen them on https://www.thingiverse.com. But I wouldn't say I have designed all of them just MOD them for this Printer." 6-12-2017: as of today, the new EX Delta is done and working. I've added springs to bed so I can adjust them. I've also added a second power supply to power the bed, it was taking way to long to heat extruder and bed at same time, so second power supply with a 25 amp power module. I've also added the firmware I used to get this Delta working. I've also included a lower base so this Delta will be and extra 2 inches higher to accommodate the extra power supply. In conclusion, everything I tried or used is added to this delta, they all work, I just tried different variations till I liked the current final version. This final version with the 300mm rods can print on a 12 inch print bed if you want to take this version to the next level. The final print area is 220x454.7 with and extra 40mm at top.

I just started printing april of 2017. Been a Cosplay peron for alot longer. I got into 3D Printing because i've spent weeks if not months building Comic-Con and Cosplay props. Since i got into 3D Printing i've made, designed and printed all my Comic-Con parts. I use to buy my 3D Printers from eBay. In fact my first 4 were from eBay. 1st TronXY x1 with a print bed of 150x150x150 2nd Tronxy P802a with a print bed of 220x220x300 3rd Kossel Delta with a print bed of 180x300 4th TronXY X3a with a print bed of 220x220x350 Home Made 5th Mega TronXY X1 with a print bed of 440x440x300 6th EX Delta with a print bed of 220x452 7th Mega EX Delta with a print bed of 405x305 8th Corexy 350x350x400 9th Corexy 400x400x400 My latest design the Mega EX Delta, prints faster and quiter then any of myother printers. When i made the Mega TronXY X1 i wanted a larger print bed so i could print my Comic-Con/Cosplay props. Turns out it printed very good, however it tock forever to print large items. so that is when i made the Mega EX Delta. I did a time test with the Mega TronXY X1 and my EX Delta, Same parts same infill same specs on both machines. and the Delta Printed item in 8 hours, The Mega TronXY X1 tock 18 hours. That is when i redesigned my Mega TronXY X1 into the Mega EX Delta printer.
