if you - as me - have more than one printer, perhaps of different types, you might be interested in the test of accuracy of the prints on these printers and wether you might print on either devices or explicitly every time on the same to get parts fitting together .. I do so and that's why I made a simple test running on all my printers to check wether I can spread prints on my printers to speed up my works just try between the holder and insertion objects which size is fitting and which level of fineness you can really achieve with your printer(s)
