RNWS sled for trackers

Sled for Eggtimer Mini tracker in the larger (3" for 7.675" nosecone) LOC RNWS cartridges.

The pic is from a prototype version. The current version has 4mm brass inserts in the verticals so the screws can be driven in through the top and bottom easily.

The top has a hole and recess to tie a string/loop to which makes extraction a lot easier.

The bottom is built to sit over the nut near a bulkhead or weight cartridge. I'll post my weight sub-cartridges for the RNWS later.

I've moved away from using zip ties to secure LiPos, but this version has them. I'll update things when I get around to it.

I included the OpenSCAD file for those who want to tweak things. It's messy: deal with it, wait for the next version, or find someone who cares.
