Description
A Spectra S1+ pump bottle holder, with no fixtures required.
I suggesting printing in PLA with 0.16 or lower layer height to ensure the threads print correctly.
Print upside down with thin tree supports for 20 degree overhang.
20% infill with 3 walls for the main body, and 5 walls for the threaded plug.
Split out the threaded plug and print to the side.
When assembling i would thread the bolt in half a turn before inserting the whole adapter into the spectra. Push it as far down as it will go, then gentally tighten the plug with an M10 hex key.
Remember it’s only plastic and will deformed if you use too much force!
The threaded plug is slightly tapered, note the “UP” text to correctly orientate it.
