Make some new Gerald Rulers #752
We need a new ruler until we get a new set of lenses for Gerald and Sophia
The orginal ruler is here so we could amend that template once we have measured up properly.
Using the tool like below gives a good cutting focus in the interim; topmost edge of tool aligned with topmost edge of the lens thread grip
Can we do a version that is self-standing? A couple of times I tried to use the distance piece in the top left and could barely reach the up/down controls.
Given the bed is not always fully horizontal and slightly bowed, it would be useful to do the adjustment in the place on the bed where cutting is being done. It can be 2-3 diff from top left to bottom right in my experience.
This would also be useful when doing regular maintenance to check the bed is level all over At Warrington FabLab I determined that 15mm gave the most precise cut so I simply glued three 5mm acrylic pieces together to act as a simple distance piece. Very simple to use and self-standing.
