Summary Re-mix of holder http://www.thingiverse.com/thing:780379 Changed to allow fans to extend out between Delta towers to keep maximum print area without running into towers. Reboot with 25mm cavity for e3d v5 that comes with my printer Now thoroughly tested The hole for the bigger screw/washer isn't quite big enough, but the rest of the body is sort enough to for around the heatsync without interfering with the z-probe movement and well away from the heater block. Tested with on large print of 140x130mm and the 120deg angles of the holder do a good job of keeping the fans away from the towers. Designed for my flsun Kossel, tho should work on more deltas... https://www.facebook.com/groups/225641914468236/
