+summary: Add aftermarket grips with a redesigned throttle tube.
+Status: Draft
+---
+
+I own a Triumph Daytona and I'm pretty happy with it. Only problem is that Triumph had the terrible idea to vulcanize
+the outer rubber grip onto the trottle tube. Making it impossible to fit after market grips on the throttle. You can see
+what I mean on the pictures. This basically forces you to always buy the original grips. They are not terrible but there
+are curtainly better ones out there.
+
+![original throttle tube with outer grip permanently attached to the inner throttle tube](images/throttle_tube_mod_01.jpg)
+
+So my solution was simple. I designed a new throttle tube that would fit the electronic throttle but have a standard
+outer diameter, so you can fit normal aftermarket grips on top. This is how it works on most other motorbikes. I did
+that in FreeCAD which has become my goto parametric CAD software nowadays. It's really nice to use since the 1.0
+release. You can find the CAD files in my [printables][printables] post.
+
+Most things were easy to measure with some calipers. I used a geometry triangle to figure out the angles. Turns out the
+details are not super important. As long as the top fits into the throttle and turns it properly, you're fine. The
+first test print looked like this:
+
+![test print in yellow PLA in low quality](images/throttle_tube_mod_02.jpg)
+![drawn angles of the top end with the yellow test print next to it](images/throttle_tube_mod_03.jpg)
+
+Everything fits nicely and the throttle works as expected. Only problem is that this tube will likely break when I
+squeeze the throttle too much. Even worse, it will break around the layer lines which will make it impossible to still
+use the throttle properly.
+
+![third party grip on printed tube next to original](images/throttle_tube_mod_04.jpg)

+
+I didn't find a way to circumvent this problem. I could've printed it with lots of supports in a different angle but
+then it would be brittle in a different direction. I could print it with an SLA printer but they also have layer
+adhesion problems under strong forces. So I decided to try out the MJF tech from [JLC3D][jlc3d] (not sponsored). It's a
+proprietary method from HP that is pretty much the same as SLS. So a fine nylon powder will be glued together with a
+fusing agent and hardened under high temperature with infrared light. This should be plenty strong to hold my grip. Even
+my FDM prints in PA612-CF are super strong but PA6 absorbs a lot of moisture and the carbon fiber is super rough and
+make it hard to glide the grip onto the tube.
+
+So here is a picture of the tube from JLC3D:
+
+![black printed_throttle tube](images/throttle_tube_mod_06.jpg)
+![black printed_throttle tube](images/throttle_tube_mod_07.jpg)
+
+It fit perfectly on the handle and my new grips hold onto it perfectly. Feel free to print your own or remix my model.
+But don't blame me if it brakes. I take no responsibility if you decide you do that.
