Chapter 1: Detach the Parts from panels by cutting the tabs

planktoscope-assembly-004.png šŸ‘ Locate the panel S1 and discover the 5 differents Parts F, P, K, J and I.

planktoscope-assembly-005.png šŸŽ¬ Flip your panel S1.

planktoscope-assembly-006.png šŸ”“ Locate the outer tabs on the edges of the different Parts. These are typically small projections of material that are used to secure the case parts to the panels.

planktoscope-assembly-007.png Gather all the necessary tools. You will need the B2 šŸŸ  Razor blade to cut the tabs.

planktoscope-assembly-008.png

  • šŸŸ£ Use the razor blade to cut the outer tabs located on the edges of the different Parts
  • āŒ Do not cut the inner tabs present inside the different Parts for now and focus on the outer tabs attaching the Parts to the main panel.

planktoscope-assembly-009.png

  • Position your razor blade on the tab as close to the piece as possible to avoid residual tab after cutting.
  • Press firmly on the razor blade, being very careful with your finger, to cut your first tab.
  • Make sure you don't damage your table by placing a flat, rigid support under the S1 panel.
  • Keep going with the other tabs of this piece F.

Once all of the tabs are cut, gently lift the case parts away from the panels. If the case parts are stuck or difficult to remove, you may need to gently wiggle or pry them loose using a flat tool such as a screwdriver.

!!! warning

Be extremely careful because this is very sharp.

planktoscope-assembly-011.png

Once you have removed your Part from the main panel by cutting off all the tabs holding it, inspect it for potential residual tabs.

  • šŸŸ£ Here is a residual tab that will need to be removed.
  • šŸŸ  Here there is no residual tab which is perfect.

planktoscope-assembly-012.png

šŸŸ£ Place your razor blade flat on the edge of your piece being very careful with your fingers and cut the residual tab.
