Intro

I designed my own beer/wineglass-holder because i couldn't find one for my camping chairs. After countless tests i finally invented the right modular design ;)

Usage

The holder is usable (means you can put a beer in it), when you connect the holder to the hirthjoint-connecter ;) 

There is a snap-pin-socket in the hirthjoin-part and snap-pin in the holder-part, which guarantees that the parts don't separate too easily. You need some force (not much) to connect it.

The hirthjoin is in 10 degree-steps, so you can adjust the angle of the holder.

Beer/wine/coffee holder

I've designed that way, so it fits for wine glasses, too. Thats why there is the cutout  on the ground.

included are

• 80mm-version
• 84mm-version for bigger coffee-cups

hirth joints for following are included

• relax chair from Bo-Camp https://bo-camp.com/en/industrial-collection-relax-chair-molfat-cationic
• campingchair from Dukdalf https://www.campingplus.de/camping-freizeit-outdoor/campingmoebel/campingstuehle/dukdalf-stuehle/dukdalf-stuhl-cha-cha-farbe-0649-silber-anthrazit
• 2mm connector for storage boards in RVs
• OpenScad-File (needs BOSL2)  for own designs.

Printing

Both parts need support - the region isn't visible anyway, when you connect them. So it's okay.
Be careful when you are removing the support from the snap-pin-part

Place the hirthconector like in the screenshot i have attached.

I've used 15-25% Gyroid infill and minimal 3 perimeters.

It works fine with a layer height from 0.2mm to 0.28mm (Prusa MK4s HF)

Happy camping/drinking ;)
