Off Grid Trailers (OGT) Expo and Pando Window Opening Prop

A block designed to hold up the windows in your OGT Expo or Pando to one of three different positions, allowing for airflow to reduce condensation when sleeping in the trailer while still allowing the window to be mostly closed, which is especially useful in cold environments when condensation is most likely to build up inside the trailer.

There are 3 positions on the block:

1. will hold window open at 7mm
2. will hold window open at 33mm
3. will hold window open at 64mm

There are 2 files, one ‘prop’, which is the actual window block, and a wall holder. 

Both parts have magnets (15x3mm disc magnets) embedded in them. These can be easily found on amazon for fairly cheap.

When slicing the file, add a pause print for each part before the magnet cavity is closed off. Assuming a .2 layer height:

• For the window block file (Window_Prop2.0 Big Magnet Final), this should be around layer 16
• For the wall mount (Wall Mount Version 2 Single Big Magnet v2) this should be around layer 19

Pay attention to pole alignment on the magnets. They need to be inserted such that the two parts are attracted to each other, that is, the orientation should be flipped 180deg between the two parts.

After the magnet is inserted, I recommend applying a layer of PVA glue/stick to help the layers above bond properly if your printer is having trouble bridging the gap. 

Beyond the magnets and pause prints, it's a fairly straightforward print. No supports needed. Recommend to print them laying down. See photos for example.

For the wall mount plate, you'll need some kind of double sided tape to attach it to wherever you want to mount it. I used a 1mm 3M VHB tape with high level of success. 

For print settings, can largely print however you want. Recommend PETG at a minimum, but PLA is probably fine too. 
 

I used .2 layer height with a .4 nozzle and 20% infill.
