3D printing
Filament, a filament dryer and an insert press for a home 3D printer. All three are on my shortlist. I have used SUNLU PETG before, in bigger spools. Each card says why it is on the list.

Keeps the home 3D printer fed. I have bought SUNLU PETG before, in 3 kg and 4 kg spools.
Note: Amazon shows a newer listing for this item (a 4-roll refill pack). This card is the 1 kg Black spool.

The maker lists a Vicat/HDT heat figure of about 70 C, and SUNLU's listing says less stringing. Maker specs: 1.75 mm filament, tolerance +/-0.02 mm, nozzle 240 to 260 C, heated bed 60 to 70 C. PETG takes in moisture from the air. SUNLU's page for this spool lists 50 C for drying. Follow the label on your spool.
Skip it if your printer is not PETG-tuned (higher nozzle and bed temps than PLA).
