Surprised how well the Snapmaker U1 is able to print ABS *without* the chamber enclosure on top. To be fair I use 12mm brims, manual double-layer round brims on corners and copious amounts of 3DLac adhesive spray to make it not warp too much. But still, kinda impressive. Part 2/5 of a new hot air AC exhaust. Fortunately I can print the (way larger) cold intake out of PLA as it never goes above 50°C… hopefully. #3DPrinting #SnapmakerU1
