Bowden Tube Holder Geeetech A30

thingiverse

This is for the Geetech A30 hotend. I have not tested it with other printers to see if bolt holes align. I was having issues with too much movement of Bowden tubes at the hot end causing them to loosen over time. I tried clips on fittings but still had problems. I created this part to bolt around the fitting for the tube and hold the tube in place. Now there's no movement at the fitting while printing! There's just enough room to get fingers to the fitting to release the tube. I still use a clip to help prevent tubes from 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 screws. If I remove this part, I will edit it to include holes for the Allen wrench to fit. If there's enough interest, I will remix it sooner to include holes. Depending on print tolerances, you may have to drill out the hole for the tube. I made it a little small and 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. I needed to remove this holder 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!
