Thước đo đường kính 2 mặt Imperial/Metric

Slide your drill bit or dowel down the slot until it stops. Check the marks for the diameter. Works for metric and imperial units. You can estimate in between marks. I usually get within 0.01" (.25mm)

I printed mine with yellow and black PLA with my CoreOne on .3mm Quality (0.4mm nozzle). I used "lightening" infill set to 15%. There are 5 top layers and 3 bottom layers. There are 2 shell layers.

I put a color stop at .8mm and at 4.7mm. The first stop is 11: 46 seconds into the print. The second stop is 44:52 into the print.

It takes 23.32g of filament and 50 minutes
