I recommend printing the peg attachement with 100% infill and 5% infill support. The mason jar lid need only support from the bottom but should not be printed with support inside the lid. I used 80% infill for the lid but its probably overkill if you put light stuff in it.
Will probably work on a better version to save the support neccessity under the lid. Feel free tu suggest changes.
Great to repurpose unused mason jar, I used my old sauce jar but any mason jar that is a standard size will fit.
Thanks to WackoPrints and AimeBuilder for the lid and the pegboard pin.
The author remixed this model.
Using the orignal mason jar lid and adding it a pegboard adapter.
