About this 3D model

First official winter Sunday evening in the UK so decide i needed a quick project. 5 mins in fusion and 35 mins printed i had this.... This is a minimalist stand that will hold two 100x3mm lithophane (note the fit is very tight, i did this by design to ensure they stood vertically). Not sure if anyone else can make use of it but please feel free. Note - the top that holds the two lithophanes in line in the picture is about 50 taller than the finished design in the attached STL.
