followed the instructions... but mirrored it. the box turned out terrible because I set flow incorrect for the pla I used(also old, slightly dusty and a bit moist) . The lid looks nearly injection molded. And for my first time trying tpu, worked great with the preloaded profile at 50mm/s (brand new roll of hp tpu) pro beginner tip (im the beginner) if you're having problems with the initial layer (with the k1 max, as im not sure on software and features of the k1) run thru all of calibration modes with your specific filaments and set your own profiles up. the initial setup on your printer is approximate for creality filaments, fine tune to get phenomenal finish. this came in clutch for my workspace at the moment, now im patiently waiting for that k1 max FDB to one day drop 🤙 I appreciate the write up as well, that took a lot of guess work out. I drilled and tapped a m6 quick connect for ptfe tubing using the top hole box, like I said mirrored for right side mounting on a 3 point spool relocation bracket. I'll def have 3-4 of these ready to go at all times...simple to swap, super simple to print, cost effective and easily stored. Thank you again !
