Slightly modified version of the original model by soasystem - reinforced bottom flange and bumper cavity. Designed to fit LeCroy scopes from the late 1990s to about 2010, built in the same form factor, where the rear feet are somewhat fragile (especially in shipping) and are near impossible to source.
These print well for me in ABS with some support in an enclosure. They are still durable when printed with good PLA, but are much more prone to shattering on impact, whereas the ABS dents and bends a bit while still holding its shape. I print them with the small end up, because the stringing on the place for the screw gets in the way when printed upside down.
Grey (difficult to exact match the original blue)
I print in an enclosure for ABS. It is worth inspecting the layers on the flat faces to make sure there is no separation.
A little cleanup of edges with a knife or deburring tool and completely remove the supports.
