It’s made with the lifting rod of a Bosch jigsaw and an M6x80 bolt. The lifting rod I used is part number 1619P12765, and I found it on eBay.
I added a better grip to it with 2 knurled sleeves, found on AliExpress. Their size is 12mm OD x 6mm ID x 30mm. They were each drilled out to an ID of 8mm, and friction-fit on the shaft of the lifting rod.
