Description
PDFA simple, solid and tight spacer for 4mm PTFE tubing.
Keeps 2 to 5 tubes neatly spaced 15mm apart for that perfect, satisfying parallelity using a dovetail friction fit.
It's best to start with the medium tightness and see if it holds together well enough while still not adding friction inside the PTFE tube (do test for any added friction, as this causes problems in the MMU2s from personal experience)
print both female (F) and male (M) parts as oriented in the file.
measurements:
| height & depth [mm] | 10 | 10 | 10 | 10 |
|---|---|---|---|---|
| length [mm] | 25 | 40 | 55 | 70 |
| tube space (tight fit) [mm] | 2x4.2 | 3x4.2 | 4x4.2 | 5x4.2 |
| tube space (medium fit) [mm] | 2x4.3 | 3x4.3 | 4x4.3 | 5x4.3 |
| tube space (loose fit) [mm] | 2x4.4 | 3x4.4 | 4x4.4 | 5x4.4 |
If you need the design adapted or otherwise changed, please feel free to ask, I will gladly help out or provide the associated .step or .f3d files. And as always, happy printing!
