seen the other spacer but when downloading all it would load of the space was gcode an if i tried to do anything to the model it changed to a stapler holder so i made my own in tinkercad by importing one of the original inserts an adding a 5mm and 10mm spacer to the back an i decided to make a version with countersunk hole, that way u can mount them through the spacers. i felt like that would be the best option vs mounting it using the shorter inserts that could cause flex if pulled to tight so this should prevent that, if i need to add it to the other inserts, i can just let me know, i may end up doing it myself so i can do it to mine. i'm still not 100% how big i'm going to go yet so i may end up making them for all the countersunk parts.
