Acrylic Mockup

I’ve moved up from Cardboard to Acrylic sheets for part mockups.
I’ve made a cardboard mockup of the part, but I couldn’t get really get any measurements off of the mockup. The cardboard kept flexing making it very difficult to position the secondary pieces to any acceptable limits. Another issue with cardboard is that it’s a soft material to measure.
Benefits of Acrylic over cardboard
1.) It’s ridged
2.) The variety I’m using is clear so I can measure bolt holes and such.
Downsides:
1.) much more expensive, as opposed to free
2.) Takes time to measure, score, snap, sand, assemble, glue.
So I guess I’ll try and use acrylic only when necessary — which this seems like one of those times.
