Unfortunately, the mp mini has a critical design flaw, which is well known, and
there are printable solutions for.
The power supply cable sits underneath the
heated bed in such a way that it starts to get worn down and can break.
The real issues were with the thermistor on the bottom of the heatbed breaking
off entirely, which would have been more of an issue if it wasn't for the fact
the MOSFET (they're electrical switches, basically) for the heatbed fried
itself. No, Really, look at this scorch mark.
Crazy, right? Luckily relatively recently I found out I was able to get PLA
printing with blue painter's tape as a surface as long as I
really put elmer's gluestick on it.
(I gave up years ago trying this because apparently I didn't
put enough glue on the surface. I still feel really silly about that.)
More recently I got an ender 3 pro from a friend, kind of as a consolation gift
for cutting ties with them. But that's an entire other story. I haven't set it
up yet, because I promised my mother I wouldn't touch it until I was caught up
with my assignments (especially this one, haha)
Another friend of mine started an etsy business using their own Ender 3, and I'm hoping to be able to leech off of their slicer settings and use them as a resource for upgrades to my own.
I took this piece of my IBM Model M Keyboard, that retains the cable, and used my digital calipers (RIP, my sweet boys) and made this model of it
I really, really love this barrel extension for the nerf sharpfire. If not for
the obvious bands on the print, and the color difference, I think this could
pass as being a stock piece, in terms of how well its design matches the rest
of the piece.
