Several different lengths of t-slot fillers to close up your table from swarf. I usually keep 2 vises bolted on the table, with the LH side either covered with aluminum or mounting a rotary table. These slots fit loosely.
Fusion360 model included in case you want to make a tighter fit etc. There are parameters to make some adjustments simpler.
Also included is a end piece, you will need 2 of these.
PLA, 5% fill, top of filler on bed.
The author marked this model as their own original creation.
