CalibCastle - Calibration test cube - stackable

thingiverse

This is my 3D printer test I have used for a while now. I wanted something that was small to print ( < 30 mins) and could be stacked or joined together so as you did the tests they built into something bigger.. In this case a whole friggin' castle!! Upload your photo's and please like.. The test is in the print dimensions and the features.. they are mostly The main turret is 24mm round the base turret is 20mm round the widest dimension (in the middle) is 30mm (top of entrance to rear) the entrance is 10mm across, with 4mm entrance hole.. with curved overhang The rear opening allows the entrance to connect to form a long wall The top tower allows another base to stack on top of it. (testing x/y/z internal print dimensions) The top wall is 2mm thick (all round) and the crenulations (bits on top of wall) are 2mmx2mmx2mm and form a retraction test. Internally there is a cone, 14mm base, with 3mm walls.. The internal cone depth is 11mm to the point. the top floor has an anchor for detail printing and also top surface testing The base tower fits on top of another test print, with the anchor on the roof being enclosed in the cone cutout underneath the difference between the base tower and top is 2mm and the overhang is 45 degrees.. Being circular the test is good for x and y and combinations of x/y tolerance.. z height is 22mm and 20mm, to the top of the wall (below the crenulations). curved surface printing over the entrance can be observed and the anchor emblem sits 1mm above the floor Any printer should be able to print this without supports with relative ease as long as it is set up correctly. It is not so much a torture test, more a confirmation everything is working right... total dimensions are 24.00 x 30.00 x 22.00 it uses 2.25m of 1.75mm filament (+/- 250cm) and takes < 30m to print. Should be good test for all materials. there is a model that forms straight walls and one for 90 degree turns.. so you can build whole castles.. If there is much interest then I will do a 120 degree one too.. for hexagonal castles! The example photos are in clear PLA and blue PETG.. they are printed with a 0.6mm nozzle so not very good. The slight elephant footing of the base is picked up when trying to fit the CalibCastles together though it was not really visible after the print. I have made a small tweek to allow stacking easier.. there is now a 0.1mm tolerance
