If you appreciate what I'm doing, buying me a coffee would be a wonderful show of support! Good quality designs take time, effort, and CAFFEINE! ;-)

A user (@JBinFL_4038) nicely asked me to create a Corner Cap version for the Original Prusa MINI Enclosure, and I decided to work on it, also hoping that others will find it useful as well. 

Since I don't have an actual MINI enclosure to test out the design, we collaborated to have it tested out on his MINI enclosure. The feedback is that either variant offered below will do the job; I just provided some options for you to choose from.

This design is similar to my design for the Original Prusa Enclosure here, but customized to fit the MINI enclosure.

NOTE: they may look very similar but are not interchangeable with each other.

Key Features:

1. Simple snap in place design - it makes use of surrounding sheet metal features in the design to snap in place!  
   • Check out the model preview to see where the snap features are.
2. The cap installs from the inside so it doesn't disturb the “look” of the enclosure.
3. Designed specifically to make room for the tie wrap anchors so it does not interfere.
4. Not only plugs up the openings in the 8 corners, it provides a bit of insulation against heat flow naturally from having air pockets trapped in the infill.

Variants offered:

     1a. Looks most similar to original - no cable pass-thru

     1b. Looks most similar to original - with cable pass-thru

     2a. Has additional stoppers - no cable pass-thru

     2b. Has additional stoppers - with cable pass-thru

As installed in an actual enclosure:

Printing Tips: 

1. Print 8x of these to cover all 8 corners.
2. I recommend to use the files with the adhesion helpers provided in the .3mf files.
3. Since this part could see higher temperatures, please use only a PETG or ABS/ASA to print this model.

Installation Directions:

1. TIP: due to variations in printer capability, it's good to check that the snap features are not fused (even a little bit) to the rest of the body.  You can push on the snap feature against the edge of a table to break each of them free - you should be able to see free movement of the snap features when you push on them (prior to installation).
2. Align one of the 2 snap features against the corresponding sheet metal features. - make sure it pushes against the edges of the metal features.
3. Using firm force (from 2 fingers), push on the other leg at its corresponding snap feature until you near a click - double check for engagement.  Try again if needed.
4. You may have to make a few attempts as you get used to the tight spaces in each corner area, but be patient and you'll get it to fit.
5. Once it clicks in, it will stay firmly in place.

TIP: Due to the cramped space inside the enclosure, it is best to do the above before you put the MINI printer inside. 

IMPORTANT NOTES:  

1. The cap will feel like it doesn't fit if you don't have both snap features aligned, but once you do and push to snap in, it will click in and hold securely.
2. The snap features allow for some variation in the enclosure dimensions and still work.
3. If it is still too tight to snap in for a corner, you might need to loosen the screws in that corner of the enclosure to allow small movements in the sheet metal as you push the cap to snap in place, then tighten back the screws.
