Description
This is an add-on for your Arca-compatible tripod plate. It does three things:
provides a lip so your camera won't twist on the tripod as easily.
provides a little extra thickness in case the mounting thread on your plate bottoms out in the tripod mounting hole on your camera - I find this to be true especially with ⅜" mounting on older cameras
provides a carrier for the 3mm Allen (hex) wrench that so many of these plates come with
Print it on the short end as shown in the two screenshots included here. I use organic supports on the bottom where the Allen key rests; I block supports on the top of the slot as they're not needed (also shown in a screenshot). I printed mine in PETG as with 100% fill but you could easily use minimal fill and I'm sure it'd be fine.
There are two versions currently here: version 1 is for plates with a 5mm deep top (not-angled) section and where the not-angled section is 39-40mm wide. Version 2 is for Acratech plates which have a 3.5mm top section and the not-angled section is a little wider.
If you have a plate with a much wider top section, this add-on won't work for you. Maybe you'll use this as inspiration to make your own? Or let me know your ideas in the comments.
