Printrbot Simple 1405 Bowden (1.75mm)

thingiverse

Hello all! Here is a new design I created last night. It's for a Printrbot Simple bowden. This was specifically designed for the 1405 simple due to the Z rod spacing, but if someone can provide me with the measurements for other Simples out there, I will happily modify it. These parts require no modifications because they use mounting holes that are already there. Please note that you will need to use the 1405 endstop hot end piece if you use the stock 1405 Y axis homing. There are only two files, and this uses an M4 nut rather than a pressure fitting (this is my first bowden, I decided to take the affordable route!). Here is a quick video of the setup https://www.youtube.com/watch?v=1bnY1_DyWbc. Check out the instructions for more information! Instructions Alright everyone, after some testing, I've found that if the extruder is mounted so it extrudes upwards into the tube, it works a lot better. I created a new part called "Untitled_RANDOMNUMBERS.stl" that mounts the motor facing up. I will leave the horizontal part available for anyone who wants it. There are also some secondary pieces that mount over the secondary nuts on the PTFE; they double down on the pressure to avoid the tube from popping out. They're entirely optional but recommended. The parts list below is for the minimum setup, which means without the extra pieces. If anyone has a question just ask! Note: This is a work-in-progress (WIP); while I have printed the parts and they ARE working great, I will continue to update it until it works perfectly! Parts list: PTFE tube with 2mm ID and 4mm OD (various lengths). I obtained mine from Amazon 4x M4 hex nuts Printed parts Various M3 screws and 3 M3 nuts (I'll determine the size once I get into the install) Enjoy!
