Rostock is a delta robot 3D printer.
This part can hold a MakerGear PEEK insulator (GrooveMount) and a bowden tube with 4 mm outside diameter. The M8 nut allows adjusting the clamp pressure so that the bowden tube won't pop out.

Print with ABS to make it more heat resistant. The original Rostock prototype uses PLA and it works okay too. Just make sure you don't pre-heat your hotend for too long without a fan pointing at it.
The top is very thin so you may need to print slowly to allow each layer to cool enough before you print the next layer. If this is a problem, use bowden_hotend_cooldown.stl to add extra cooling time for each layer.
- Drill the clamp hole open to 4 mm.
- Cut the three slots open with a sharp knife if necessary.
- Add a stainless steel M8 nut on top but don't tighten it yet.
- Push the PFA bowden tube all the way into the clamp.
- Tighten the M8 nut, but not too tight. Hand tight should be enough.
- Drill the inside of the PFA tube open to 2 mm if necessary.
- Attach with two M4 nuts and Wade style plywood GrooveMount.
I recommend flexible clear metric PFA (Teflon) tubing with 2 mm inside and 4 mm outside diameter, e.g. http://www.mcmaster.com/#catalog/118/137
