Fillet Gauge 1-25mm

thingiverse

With the "FilletGauge-PartOne-MK2" you can measure the diameter of rounded corners with a maximum of 90° degrees (like corners of mobile phones, e.g. if you want to design a case for it). The diameters can be from 1mm to 25mm - in 1mm steps > that means: you can measure radius in 0.5mm steps from 0.5 to 12.5mm. The "RodFilletGauge" can be used to measure the diameter of rods, poles, pipes etc. between 1mm and 25mm. The angle of the segments is 150° degrees. That means: You must be careful in measuring, because the gauge will not surround half of the pipe. The "FilletGauge-PartTwo" is an experiment. Due to the 150° segment degree, you might only be able to measure inner fillets of e.g. frames where you can slide one fillet after the other. For fillets that are inside of a surface, you need fillet gauges with only one dimension on one side of the gauge. Specifications & characteristics: metric measurement numbers show diameter in mm (not radius) fillet diameters from 1mm to 25 mm even and odd diameters on opposite sides 4mm attachment holes on both edges (e.g. for key chains or for hanging up) For the measurement of notches, please check out my other thing: http://www.thingiverse.com/thing:2134611 For a smaller version (printable on smaller printers) please watch out the MK3: https://www.thingiverse.com/thing:2599918 Print Settings Printer: bq Hephestos 2 Rafts: Yes Supports: Doesn't Matter Resolution: 0.2 least Infill: 100% Notes: My Hephestos 2 seems not to be able to print objects with squared corners. My first attempt "warped away" (like many other squared cornered objects I tried to print). So I needed to invest double of the print time (and material) and had to add a big flat raft beneath the gauge. An other attempt with a brim also warped :-( And bq still doesn't offer a heated bed for this model. How I Designed This Designed with FreeCAD It was hard to get this up and running on FreeCAD. I made one sketch only for the base and it took me plenty of time with all the construction lines. Moving around and centering the whole segments was hard to due - FreeCAD seems not to like that many constraints at once ;-) After finishing the sketch, I just had to add 25 Text Labels and "pad" them up. Finally I made a fusion of all objects and made a cut for the two holes.
