I got home with the new domino and found out that the hose attachment (dust collection required) isn't same as my other Festool tools. grrrr. Didn't want to spend more money for a 3rd party adapter.
So, it took several attepts to fine tune it but worth it as it fits nicely on the DF 500. It clicks into place and holds tight. If the hose connection side doesn't fit your hose, the fusion 360 file has two components, one for the tool side and one for the hose side.
Walls are 2.5mm thick and I printed on 0.4 nozzle using the default bamboo setting “0.20mm Strength” setting with PLA. Took 1h3m to print.
