Bill of Materials
- PTFE Tube Coupler x 2: available here https://eu.store.bambulab.com/products/ptfe-tube-coupler?id=46902128443740
Description
This is a simple snap-on extension that snaps to the A1 mini PTFE tube connector. Depending on selected variant, one or two PTFE tube couplers can be mounted on the extension.
There are currently 3 variations of this part:
- 1x extra PTFE tube coupler on top of original connector
- 1x extra PTFE tube coupler below the original connector
- 2x extra PTFE tube couplers below the original connector
Notes and recommendations
- I only tested printing the parts in PETG. PLA will probably work fine, but the snap fit is very tight, so scaling up by 1-2% may be needed.
- Refer to the part documentation regarding coupler orientation → filament needs to enter from the black side and exit from the blue side.
