My wife wanted a festive napkin holder for thanksgiving. I used Tinkercad and created this Turkey napkin holder and then had to figure out the scaling. I ended up scaling my original design about 239% to get a size that she thought was good.
Stringing is based upon your specific filament. I've printed 6 of these this season and I had no stringing. I used a brim because what I found is if you leave the door open and the top off you can get some warping when printing PLA. This is because the AUX fan blows cold air right on your part on layer 2 which can cause the part to cool to fast and lift. I leave the door and top off because of heat creep coming up the nozzle to the extruder causing jams when using the AMS. I had a 2 week discussion with Bambu Support about it. Anyway I hope you enjoy.
