Delta sander adapter for Bosch, Milwaukee, Dewalt, Einhell and Makita

Designed for the Bosch GOP250, but it turned out to be compatible with the Dewalt DCS356B cordless, Milwaukee 2626-20 M18, Makita TM3010CX5, and Einhell Varrito.
Printed in PLA with five layers (side, bottom, and top), with 25% gyroid-type infill, with support, and a 5mm gap.
I assembled it with 2mm EVA foam and glued Velcro.
It's been used for 15 sandpapers and so far it's still intact.
NOTE: I tried making it in PETG, but the glue doesn't stick.
I hope you enjoy it, and I look forward to your feedback to improve it.
