This universal spray can holder builds on the many broken models I have found around my shop, adressing the failure points I have most commonly seen.

I found the last deteriorating can trigger in my shop, modeled it as closely as I could, then strengthened the points where I have found breaks and decay.  I also added features to make it universal for most spray cans.  

Print the main body in pla, pla cf, or possibly petg cf.  Then print the front cover in tpu or flexible platic so that the locking tabs on its rear don't wear quickly.

I hope to post a new model pending how it fairs in my shop.
