Bowden Tube Holder Geeetech A30

thingiverse

This is for the Geetech A30 hotend. I have not tested it with other printers to see if the bolt holes align. I was having issues with too much movement of the Bowden tube at the hot end causing it to loosen with time. I tried clips on the fitting but still had issues. I created this part to bolt on around the fitting for the tube and to hold the tube in place. Now there is no movement at the fitting while printing! There is just enough room for me to get my fingers to the fitting to be able to release the tube. I still use a clip to help prevent the tube slipping at that point. This prints in two parts, the base and the tube holder. I didn't create enough space for my Allen wrench to fit, so I had to bolt the base onto the printer first then glue the top part onto the base. This isn't a big issue, but when I have to remove the part I will have to cut off the top to access the screws. If I remove this part, I will edit the part to include holes for the Allen wrench to fit. If there is enough interest I will remix it sooner to include the holes. Depending on print tolerances, you may have to drill out the hole for the tube. I made it a little small and I had to slightly enlarge the hole for my tube to fit. The benefit of this is that my tube fits tightly in this part which helps prevent it from pulling out of the hot end. EDIT: 5/13/2019 I needed to remove this holder and because of how I designed it I had to cut the print. I redesigned the top to have two holes in it so you can easily get the Allen wrench to the bolts. This is the version 2 file. I also did a version with a bigger hole. This one doesn't fit tight, but it still reduces movement at the fitting. This file allows you to remove the PTFE tube without removing this holder. ENJOY!
