Bosch PEX 300 AE to GAS 35 adapter

This adapter connects a Bosch PEX 300 AE random orbital sander to a Bosch GAS 35 vacuum cleaner. It features a snug, secure fit on the sander, so the hose stays firmly in place and won’t come loose during use — even if the hose gets pulled or twisted. I printed and tested the adapter in PETG, but PLA should work just fine as well.
