Following on from the repair of the top mount pad here…

… this time it's the bottom buffer washer that reduces the impact if you loosen the main rack too much and the top platform slams down into the base! My buffer had perished and crumbled away much like the top mount pad had. So I fixed it with TPU :o)

I printed with 2 walls, 3 tops and 3 bottoms, 20%  gyroid infill, Eryone Clear TPU Shore95A so any TPU should do but possibly more infill and more walls if you have a very soft TPU. My Elegoo Neptune3 Pro has to print TPU excruciatingly slowly, 10mm/s on the bottom layer and then 20mm/s for the rest, takes forever but the results are worth the wait, the Eryone Clear TPU is gorgeous stuff and doesn't over-adhere to my textured PEI plate if I use an UNHEATED bed. If you use a smooth PEI plate then you probably need a good coat of gluestick to make it stick just right - I can do that on the smooth reverse of my PEI sheet but I also need to heat it to about 35C so the gluestick dries quickly and it sticks ok then. 

Layers 0.2mm, nozzle 0.4mm. Not particularly critical

To fit the washer on this model you need to undo the screw that retains the crank handle, slide that out and you can slide out the main shaft sp the new buffer can be fitted. Be careful, I learnt the HARD way that you can't just pop the main shaft back in again as there's another little sleeve inside the main tube which snags and then gets pushed out. You need to unscrew the main vertical guide tube until it comes away from the top section, and then you can insert the sleeve and then the main shaft and finally reinsert the main tube into the top housing. Another warning from someone who learnt the HARD way, hahahahaha, my finger is REALLY hurting now because I didn't realise the main vertical tube is the adjuster for that inner sleeve, and controls how much friction is on the main shaft - I hadn't done it up snug and the head assembly weight spun the crank handle and slammed down on my finger pinching it violently and raising a nasty blood blister. Owwwwww!

This is a really nice tripod though, despite its age, and it's now fully refurbished :o)
