Midea Bolt / Peg

Edit 6/9 - removed V4 because they don't work. At all. 

This is the Midea "Bolt" / Peg used to hold up the Midea air conditioner panels. There are three versions: V2, V3, and V4. V2 is the easiest to handle and remove by hand but adds more of a gap between the window and panels; V3 is slightly shorter, and V4 is an ultra-flat version that most closely represents the ones that came in the panel (but will be very difficult to remove, and will likely break in the process). 

These are optimized for 3D printing BUT come with significant limitations - for a FFF printer, they need to be printed with the head flat on the bed, which can cause the peg to shear off in use. As a result, these are intended solely as a 'semi-disposable' alternative in case you lose your original parts. With that said, I have had OK luck printing these with 3 walls and 20% infill in PLA, although something like PCTG would be better. You can also print them in resin which should prevent the layer-shearing issues. 

Both V2 and V3 peg/bolts will cause a slight gap in the window; V4 should be much more flush at the tradeoff of being difficult to remove. 

These work for me in the Midea Duo, but it should also work for the other Midea air conditioners.

Attached pic is V2 printed in clear resin. It's a bit chunky so it does cause a decent gap (~3mm) in the door.
