Spiderbeam 10m Bottom Cap with Peg and Wire Hole

I created custom replacements for the original bottom screw-on cap of the Spiderbeam 10m pole.

One model includes only a 24mm washer and a M8 nut so a M8 dowel screw can be inserted into the bottom as a peg. If you feel like it, you can use a shorter screw just enough to hold the bottom steady, that would prevent from breaking anything if the pole would accidentally tilt or fall. The one I used on the pictures is long enough to hold the pole straight up with 3 elements extended. That I found to be pretty useful when I dismantle the setup, I can just lower the mast by 3 element pieces, then roll up the wires and strings with the pole not going anywhere.

The larger cap also includes a wire hole for a 40m monoband vertical, then the wire can run inside the mast. Although I abandoned that idea for the impracticalities of lowering the mast with the wire inside.

I have left space for 10mm thick foam for more sponginess as I coiuldn't find any kind of foam as stiff as in the original cap.

I used PLA with 0.1mm layer height, no supports. I also recomment using a few mm brim to prevent warping on the rounded edges. Also be sure to calibrate your pressure advance to get the best quality overhangs on the threads, although there is a bit of clearance for blobs on the underside of them.

Don't forget to add pause commands for the washer and nut. For proper layer adhesion on the washer I recommend sticking one non-overlapping layer of electrical tape on the washer's top surface. Leave the hole uncovered ;) Make sure to fit in the 2,4mm Z space I left for the washer, if there is any burr on the washer that would make it stand up a bit just choose an other one.

Please note that the pictures are of earlier versions, I made some modifications after I printed them to improve things a bit.
