I made this cap to utilize a hole cut out by the previous owner to run my sonar and power cables through.  I mounted my transducer inside the hull and shoot through the bottom of the kayak.  It should also help minimize water getting into the hull.  I also used a backing plate to give the screws a little more bite along with a good dose of marine grade silicone.  When not in use, I can just twist the cap 180 degrees and keep any unwanted bugs out.

Attachment points to secure a Tuff Krate in a Feel Free Lure 11.5 kayak.

The 1/4" lock nut will accept a t-bolt/track adapter.   

I also added a model that uses a 1/4" barbed insert for added strength.  I was able to get the insert into model by using a soldering iron to melt it in.

The M8 version accepts a M8 nut to attach to the M8 bolt stud that holds the seat down.

Update 06/04/21:  recently tested these tie downs out on a two day river float.  They appear to have held up and worked to keep my Tough Crate in place through swift water.  I ended up attaching cut to fit bungee cords on the crate and used a carabiner to attach them to the eyes.

This adapter is used to attach a Shoreline Marine zig zag cleat to the goofy FeelFree unitrack.  I will now be able to use the anchor trolley more efficiently. 

I designed the adapter to slide in from the end of the track.  They are not intended to be drop in.  Make sure that the longer side of the adapter is facing outward. The adapter uses the included lock nuts but I bought some stainless 10-24 oval head machine screws 1/2" long.

Update:  I was able to test the anchor cleat and the printed parts out.  Everything held up well over a week long period in substantial current and a lot of big boat wake.

The tensioning knob on my 8 ball rudder control handle kept backing off while in use.  I designed this knob to accept a m6 nylon lock nut to prevent that. I also integrated the Feel Free logo as a cap.  It is a tight fit but I was able to get it to work.

Feel Free Lure 11.5 Kayak center console pod spacer.  This spacer will allow the console pod to be used if the Overdrive peddle unit is not needed for the trip.  I had intended to bolt it to the pod but found that a good marine silicone was suffice to hold it in place.  Now the pod will rest against the brace used by the peddle drive unit and allow the pod to be secured in place with the strap.  A variable that must be taken into account is that your drive unit plate might be slightly higher or lower than mine so adjustments to the STL may be required.  I left a notch cut out in case there is a need to reinstall the original hardware.

One way scupper plug for a Feel Free Lure 11.5 kayak.  I used a Nerf Rival gun foam ball for the one way valve.  I also inserted a piece of filament or grass trimmer string into two drilled holes toward the bottom of the plug and welded it flush to the sides in order to retain the ball.
