toolhead cover for k1c

made by rick tuckerUpdate: Added a new version that is compatible with both the K1 and K1 max. The cooling performance is unchanged and the old versions are still there if you prefer those. The changes are: Updated appearance - Like me, it looks better in person than in a picture. Reinforced the top holes. - I had a break around one of them when removing the cover. One file with for K1 and K1 max. This also makes for easier access to the Lidar port in case someone wants to make a remix with LEDs. Features: Better cooling than the stock cover for overhangs (all directions) and bridging. The test prints below were printed back to back with the same g-code. The difference is consistent with many test and regular prints. The air flow difference can be felt by hand (and seen if you want to put a cup of water underneath it).
