I want to create an enclosure case for a Raspberry Pi 3B+ with a GrovePi Hat on top and an LCD display attached.
I found design files for a laser cut case for a Raspberry Pi 3B+ [1], as well as the details of the GrovePi [2] and the LCD screen [3]. Since I'm new to laser cutting, I would like to start from the design files for the Raspberry Pi 3B+, and extend the height of this box a bit.
What would be the best way to approach this (e.g., in InkScape)?
Here's how I would do it in Inkscape
Resize the page to give yourself a bit more room.
Unsing the Select by Nodes tool F2 select, then convert the little rectanglular holes to paths using Path > Stroke to Path
Ungroup the pieces, regroup the top two pieces together
Rotate the top group so the pieces are the same way up as the bottom two pieces
Using the Select by Nodes tool F2, select all the paths you want to move. Holding down Shift while clicking will allow you to make multiple selections
While still holding down Shift, select the nodes you want to move by clicking and dragging rectangles to encompass those nodes. The selected nodes will turn blue.
Nudge up using the arrow keys
Here I show steps 4 to 7
The case cutline file you link to is .svg, and will work in any competent vector art or CADD program, from InkScape to Affinity Designer to Adobe Illustrator to Draftsight (was free CADD, now $99 license and darn good too - I use it in architecture to replace AutoCAD and it does everything I need) or even AutoCAD.
However, the two other design files you linked to were SolidWorks files, so for free 3D engineering CADD apps I'd look first at Onshape - it should read these and has a really good robust system, supports assemblies and so on.
Hope this helps.
