Front Bottom Unit - M3
2019-12-13 Caution! I've printed it out by myself and found out (after 13 hours) that I made a mistake and that the holes didn't fit.
I fixed it and made a test print of the specific area.
My apologies for everyone who started printing.
A remix of the front bottom unit provided by countspatula (https://www.thingiverse.com/thing:1394492) so metric head screws M3 will fit. I bought my screws from the hardware supply in Germany and the heads were too large for the holes.
