A simple set of parts to set one CFS unit over another with enough clearance to open the lid.

This print requires a K2 Plus or access to a printer with the same or larger bed.

Material Notes

Some of the plates need to be printed twice. Total material use is around 2kg.

This was designed to be printed with PETG for strength and flex. My final version here was printed using SUNLU High Speed Matte Black PETG. Your mileage may vary with other materials.

Print Settings

Most of the settings are tuned to ensure maximum strength where needed.

Some of the parts do use supports. Normal (Snug) will produce the best results with the least filament waste. The Top Z distance in the 3mf is already set to 0.27. If you have a preferred value for your particular filament, feel free to substitute. If you have issues with support quality, trying incrementing the value by +.005 for more support or -.005 for easier release. My prints came off cleanly and the supports remained on the bed.

Printing Notes

1. Bed adhesion can be tricky for the long cross bar. I have found it prints best when oriented from front left to back right. I've printed it successfully with both Hyperlok and glue stick, but in both cases, ensure to add more between prints.

2. The various threaded parts print fine for me without supports. All the threads are the same size. You do not need to meticulously clean out any stringing or stray filament. Take any two threaded parts, rapidly screw and unscrew advancing slowly past any parts that bind. They will quickly and easily clean themselves up with minimal fuss.

Assembly

Print all of the plates and print a second copy of plates with an x2 suffix.

1. Take a Tube Foot and slide the loop of a Bottom Front-Rear Bar over the tube. The Bottom variant of the Front-Rear Bar has a slightly higher profile that matches the height of the foot's base. Orient the bar so that the bottom of the Tube Foot and the bottom of the Bar are flush.

2. Take a CFS Base - Front-Left and slide it over the Tube Foot. The cutout on the bottom of the piece should snugly cover the Bar.

3. Slide the loop of a Side Bar over the Tube Foot

4. Screw an Extension Tube into the top of the Tube Foot

5. Repeat and screw another Extension Tube into that

6. Screw an Upper Tube Base into the top of the second Extension Tube

7. Slide the loop of a Side Bar over the Upper Tube Base

8. Slide the loop of a Top Front-Rear Bar over the Upper Tube Base

9. Take the other CFS Base - Front-Left and slide it over the Upper Tube Base. The cutout on the bottom of the piece should snugly cover the Bar.

10. Screw a Tube Cap into the top of the Upper Tube Base.

Repeat the above steps for the other three corners substituting the corresponding CFS Base component and using the opposite ends of the corresponding Bars. Ensure to tighten all the screwed parts when you are complete.
