This model has been created to make it easier to position inserts into

I found it hard to position the insert and t-nut straight and easy to ruin the t-nut when heating, so I modelled this holder of 2 nuts for support.
I printed this in PLA but most materials should work well. Printed with a 0.4mm nozzle and 0.2mm layer height.
The author marked this model as their own original creation.
