In pottery making there is sometimes need to check bottom thickness in order not to have too thick bottom or not to trim too much material out. Measuring in 1-2mm accuracy can be a challenging with hand held rulers or tape measures especially if the work of art is odd in shape like not even rim like in this photo.
Picture presents my one print foldable solution for bottom thickness measurement stand holding measurement stick (gauge itself) in place. Gauge thickness is ideally 5mm to hold upright.
Desing target was to have large enough gauge stand from printer area of 250x210mm. Target was also to have one print for all parts with no need for extra parts and minimal assembly.
Prints are made with MK4 0,4mm nozzle 1.75mm PETg. Layer height 0,2mm, two perimeters and infill 25% grid oriented 83 degrees. Supports everywhere.
Gauge stand is printed as folded. After cooled part joints are folded out with force breaking the supporting material in the joints.
My attempt to design/print gauge itself was almost successful and this design needs some improvements.
Update: idea of 1mm string lines floating in air started to work somehow but where hard to read or count them in practise with different light and shadows conditions. After seen Thickness gauge by Heliosmaster_32831 (originally uploaded by nat_blundell) I decided to change ruler operation principle from absolute mm lines to relative slider gap.
Stand itself is not altered but the gauge parts are updated and sliders added to files.
Gauge parts and sliders works quite nice with PETg as material has some flexibility.
