While assembling an 8020 15 Series assembly in the lab, we noticed that the 5/16" Slide In Economy T-Nuts we were using were not staying in place well. I designed a quick part that could hold the T-Nut in place during assembly. This will work with 8020 part numbers #3278, #3263 and #3285. I printed 99 at a time and it was less than $2.00 in PLA. I know this is a pretty niche model, but it may help someone!
