These take about 6g of filament on 0.2mm layer height, 15% infill. 150mm/s print speed with first layer at 80mm/s. Takes less than 20 minutes. No supports or brims needed. I always end up with that small strip of filament in a color I probably won't buy again for a while. This will be a great option to use up that last little bit. Have only "used" it once so far but I keep playing with it sitting at my desk for the last few days and the quality feels pretty good.

Printed two of these so far on 0,2mm heigh with 10% infil in PETG, both work and have been used without any cracks so far. Will try a few in 0.28mm as well

great model aside the fact that the spring cracked after a couple of uses (reinforced it with a dab of superglue and it works great)
