This is a replacement part for the Whisper foiling catamarans ride height T part. It is printed laid down so to benefit from increased strength vs. the original part. As a tradeoff, it needs to be printed with supports.

For enough strength, I recommend printing in FormFutura ASA (ApolloX) material, which is UV, warmth and water proof.

T-Part

This version does not use a metal thread insert as the original one does, but instead receives the threads directly in the plastic using an M8 thread-cutting tool. So please check out print settings below, as those are unusual yet important for robust threads.
* supports from bottom up only (no supports for the M8 hole needed)
* make sure its printed horizontally
* i recommend approx 2.8mm shell/roof/floor
* M8 thread cutter
* use a 9mm drill to just clean-out the 9mm hole for the arms

Update 2019-11-09

There is now a version with Stainless Helicoil metal insert. It is not clear at this point whether the metal insert is required at all when using the print method and material as abovementioned.
You will need M8x1.25xD3 Helicoil kits like this and long enough stainless helicoils.

Lever Arms:

• drill 2.5mm holes for the 3mm screws
• cut M3 thread into 2.5mm holes (hint: using only 2 of three cutting tools, makes the fit for the screw tighter so it doesnt get lose as easily; a tiny bit of glue helps additionally to lock the screws)
