A press to press powder into pellets/pills.
Needs a M10 screw with hex-head.
All parts exept for the funnel (Trichter m10) can be printed without supports. I suggest using a thick wall size for strength.
I reccomend slighty upscaling the models in the x and y direction, especially if your printer is struggling with tight tolerances.
What worked great for me:
Print “Zylinder m10 oben” at 102% scale in x and y direction.
Print “Zylinder m10 unten” and “Trichter m10” at 105% scale in x and y direction.
You might need to post process the smooth holes in “Griff” and “Zylinder m10 oben” (the lowest cm, not the threads) with a 10mm drill bit for best results.
How to use:
- Add the m10 screw to the grip.
- Screw the grip into the cylinder for a few mm.
- Screw the funnel onto the cylinder.
- Add your powder (There is an experiment in the “Chemie, aber sicher!”-publication by ALP Dillingen, if you happen to be a bavarian chemistry teacher: 26_Ph_ASS_Isolation-Nachweis_Funktion_Hilfsstoffe)
- Unscrew the funnel and screw the endcap onto the cylinder.
- Press your powder until you feel the endcap bulging. Tightening the srew further might result in destroying your endcap.
- Unscrew the endcap and use the screw to press out your pellet/pill. Done!
