Good for gaskets to phone cases .
other materials available on request, but will need added time for shipping .
A good list of materials with descriptions is here https://www.3dnatives.com/en/plastics-used-3d-printing110420174/#!
all properties listed are generic and will vary slightly from brand and lot . (properties sourced generically and may not be accurate .)
Electrical,micro-controllers, machining, and mechanical ability to get your project from start to finish.
I do electrical ,circuit repair, part replacement,son Arduino, and micro controllers, as well as having a stock of parts , and the ability to get parts on request
refurbished appliances available when applicable, as well as minor repair.
(refrigerators and air conditioning are not repaired)
I can do 3D printer repairs , as well as modifications . I can also educate on the topic .
Making projects ,testing and parts all ad up , and I am currently unable to work and on a fixed income . If you would like to help me out or would like to fund a specific idea or project please donate .
