K2 Plus - CFS Riser, Ventilation, and Storage

Boost Me Making designs takes time and filament for prototyping. Boosting or supporting helps keep my designs free. Thank you! Update 2025.02.06

Some people have reported that when they printed, the tolerances were too tight for their printer to handle. The original, now called “Tight”, version has tolerances of 0.14 mm. There is now also a “looser” version that has tolerances of 0.21 mm. This applies only to the seam down the middle front-to-back, as it was reported the other seams were fine. There is a test print for each of these, and I highly recommend printing it to make sure your printer and desired material will work.

End of Update

In V1, there was a minor design flaw in Parts 3 and 4. There is a part on the bottom of the CFS that juts down that I did not account for. If you already printed parts 3 and 4, you can print 2 of the feet risers and drop them into the back two slots. You will never know the difference.

I started from benlevi's BLV - AMS Riser  concept and completely rebuilt it for the K2 Plus. Credit to them for the original concept, but this is a new creation.

This is a big print, and has been a big effort for me to make, so I hope that you enjoy it.

Depending on the parameters you use, you are looking at 3-4 kg of total filament and ~80 print hours. The K2 Plus gets toasty when the chamber heater is turned on, so I would tend toward PETG or greater thermal stability for the main body, but I haven't tested, so who knows.

You will also want TPU or some other flexible filament to accommodate the gasket for the glass.

As I said, this is a complete redesign of the original, incorporating many changes to improve printing. Gone are the fillets, and replaced with chamfers to minimize the need for supports. Angles are kept to a maximum of 60 degrees so no supports are needed. The seems are more effectively hidden to improve appearances. Hidden pocket screw holes are added if you want additional strength and rigidity.

Assembly is the same as the original.

I want to always keep my designs free for anyone who wants to use them, but this does take time and effort. So if my designs are worth something to you, please feel free to support my work

***IMPORTANT NOTES - READ ME OR YOU WILL WASTE A LOT OF TIME AND FILAMENT***

- All of the main body parts should be printed with supports set to on, with: - Threshold angle: 25 - On build plate only: checked - Remove small overhangs: checked - Support/object xy distance: 0.35 - Although completely optional, there are screw holes between all of the parts to pull them snuggly together. I put these in thinking that the tolerances may be a little loose and I would want them to all be snug, but after assembly, I found that they are really not necessary. But you can still use them. They are for M3 bolts, and I will put together a list of lengths shortly. DO NOT install bolts that are too long as they will push through the other side - The included gridfinity is non-standard. They are 38.5x38.5. - The included baseplate and larger bin are designed so that the you remove the large bin and slide the baseplate forward to get assess to all of the smaller bings. - The CFS buffer should be mounted to the back of the CFS, NOT to the machine itself. It works perfectly fine and is one of the two mounting options in Creality's user guide. - SOme people printing ABS and ASA found that the holes in the dash were too small. I believe this is because of shrinkage. If you are using these filaments, try the dash with larger holes
