#Rotary cutter with offset pointer for sewing patterns Can be used to cut fabric pieces from sewing patterns precisely while adding a margin(allowance) using a variable offset pointer. No need for chalk or removable pen around the patterns. ###Remixed from: Improved Rotary Cutter for 45mm Blades by potatoad (https://www.thingiverse.com/thing:4614659) Marking Gauge Tool by azorko (https://www.thingiverse.com/thing:2851783) Dip Extractor 1000 by CollegeEngineeringStudent (https://www.thingiverse.com/thing:3329045) (thanks all for the good work!) Based on potatoad's design, I added azorko's marking slider and the bigger handle from Dip Extractor 1000. ###additional parts needed : 608 standard bearing 45mm blades (e.g. from prym) Pencil screws: 2x 2.5Mx8mm + nuts 2x M3x10mm 1x M3x8mm 1x M3x20mm + nut M5x16 + wingnut Wingscrew M5 (or M4) x 20 + nut ###Assembly : 1. combine main parts using 2x M3x10mm screws 2. insert bearing, tighten M3x8mm screw to hold in place 3. assemble bracket on main part by 2x M2.5 x 8mm screws and (4.) insert nuts in bracket 5. use a M5x16mm screw for the blade axis: 6. insert screw in the bottom cap 7. middle cap and top cap hold the blade on the other side (be careful when handling blade!) 8. use a M5 wing nut or similar to hold blade axis in place insert M5 (M4 will be ok as well) nut in the bracket for the slider screw 9. use an M5 wingscrew to fix the slider from above (alternatively print suitable knob for M5 ;-) insert a pencil (or similar) as indicator, fix by M3x20mm screw and nut 10. to change position of pencil, bracket can be reversed when needed ###3D printing parts : STL files : Cutter_mainpart1.stl Cutter_mainpart2.stl Bracket.stl blade_bottomcap.stl blade_middlecap.stl blade_Topcap.stl Slider.stl for better visibility of the slider scale, use a color change (different material) of one layer underneath the scale of the slider.
