inland spool splice

I do 0% infill on the bolt and stud. But up wall and floor thickness to 6mm
Inland filament spools have a seam where they put the 2 half's together very easy to cut in half and drill some holes to put it back together. than i do glue one side in and let the bolts or studs do there job on the other. Than i do print out the main body at 5 mm height or so just for and easy way to dill holes and check final fitment before printing the whole thing
