After printing the Luftwaffe style pedals from Svejseko https://www.thingiverse.com/thing:2739648 i felt that the hole at top end bothered me so i made a little addon to fix it.
Print two of each part and glue the barrel to the plate with a couple drops of CA glue.
Depending on your printers tolerances you may get a snap fit or it might be a bit lose (i got one of either), if you like them just add a drop of glue under each one to fix them permanently.
