Various mounting blocks

My company Seenov (seenov.com) has Pick&Place machines and I wanted to make an adjustable off-ramp for the PCBs.
There are a fixed rail and an adjustable one mounted on a leadscrew with bearings. To assemble all the parts I needed various mounting blocks for screws of different sizes. These are the ones I created.

Thanks to https://www.thingiverse.com/stackmagic

for the bearing mounts.
