Pantograph for scaling up using 608 bearings
thingiverse
To build this model, you'll need: 5x 608 bearings, 4x M5x15+ screws along with their corresponding 4x M5 nuts, 3x M3x10, 15, or 20 screws paired with 3x M3 nuts. Additionally, a single M3 and one M6 spacer are required. For assembling the connection between arms, refer to this YouTube tutorial: https://youtu.be/rPOF8rcytYY Since you may not find an identical "pointer" like mine, I enlarged the hole to 1.4 mm for ease of modification in files named "vnitr rameno vedl" and "vnitr vlozka". The scaling up ratios can be found on one of the attached photos.
