Original Prusa MINI Enclosure (OPME) - Corner Caps (from the Inside) - Lightweight version

Description

This is a remix of Original Prusa MINI Enclosure (OPME) - Corner Caps (from the Inside) by @BuildX. Please check the original model page for more details and instructions. 

This Lightweight version weighs half a gram less and provides more space compared to @BuildX's version for cable management. By eliminating center material, the corner caps have less interference with any cables, tubes, or LED strips that might be installed in the enclosure.

My Printing Setup

• Layer Height: 0.15 mm
• Infill: 0%
• Supports: Not required
• Brim: Not required

Original model 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:

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

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

     2c. Has additional stoppers - without center material

As installed in an actual enclosure:

Printing Tips: 

1. Print 8x of these to cover all 8 corners.
2. I recommend to use the file with the adhesion helpers provided in the .3mf file.
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.
