Stiff anti-buckle feet inserts for Creality K1 Series
Description
PDFThese stiffening feet inserts are a great first mod, without the need for tools, experience or fancy print settings. Simply print 4 inserts and press them into the feet of the printer. This will eliminate the excess slop that can cause folding / buckling.
SUGGESTED PRINT SETTINGSMost 3D printer parts should be printed using filaments like ASA, ABS, PA or PC to withstand the heat from the hotend and printbed. Printing these filaments can be very challenging and requires high chamber temperatures to avoid warping, so these feet were designed to be printed in PLA without any fancy settings like supports or a brim.
PLA is easy to print and doesn't require high chamber temperatures, but it also doesn't handle high temperatures so it is not suitable for use inside the printer. The feet do not need to be able to handle high temperatures because they sit out of the way of the heat and are insulated by the rubber feet, so PLA is fine for this application.
You should be able to print these feet inserts using the default settings, but here are some of the most important settings to check if you are having trouble:
| Filament Type: | PLA - Any type of PLA will work (PLA, PLA+, Hyper PLA etc) |
| Nozzle Temperature: | 220°C - Most PLA brands print best between 190°c and 230°c. Since the K1 series prints quickly, setting the nozzle temperature towards the higher end of the range will help the hotend to keep up. |
| Bed Temperature: | 60°c - Heating the bed to between 50°c and 60°c will help the print to stick |
| Part cooling fan: | 100% - PLA likes to be cooled quickly in order to harden and increase the surface quality. |
| Aux cooling fan: | 70% - If you have an aux cooling fan (on the right side) it can help to cool down the print. |
| Infill Pattern: | Gyroid is the best all-round infill type, offering a great combination of strength in all directions, fast printing, filament saving and does not cause buildup and scraping issues like grid infill. Click here to learn more about infill types. |
| Infill Amount: | 20% is fine. It is almost never practical to use more than 50% infill, because part strength mostly comes from adding more walls. |
| Wall Count: | 5 walls will provide lots of strength. |
| Supports: | None |
| Brim: | None |
| Layer height: | 0.2mm |
There should be a tiny gap at the bottom so the feet do not touch the underlying surface. You may need to scale the model height or adjust print settings if they stick out.
