Delivery Stamps Pack

I love the design of these, however, I did notice a few issues. For references I'll split the model into two parts - the top where you hold your hand and it tapers down can be the stem. The base plate, where the design is, shall be the puck... On the exterior of the puck surface, there is polygonal fracturing, where some of the design isn't round like it should be and seems to have materials taken away, in the original CAD model - This does show up on the print. The stem is well made and I love both the side and shape of it. It fits very nicely in the hand. One point of contention that I could see with the design of the mating surfaces between the stem and the puck is that the center of the stem is mostly hollow, and should probably be transitioned to either a 50+% infill, if not just a full solid brick of wall loops. The connection point is also quite thin. If this stamp is to be used every day, sometimes in cases where multiple people could be handling it, and/or in a hurry, it should be reinforced to be durable. It does take a bit of excessive force, more than a person acting in a 'normal' behavior should do, but if one was angry or if the pieces was dropped, and kicked or stepped on, it would break at this point. I was able to break one during testing. Photo available if desired. Since this model is a SDF License, with no derivatives or remixes, I opted to allow the original designer to make this modification/adaptation should they choose to modify the item in its originality. I would highly encourage that the model be printed with a TPU layer or some other SOFT material, for at least the bottom 7/64", or 3mm, because when the model was printed in PLA and tested it was found to have inadequate stamping abilities on corrugated cardboard surfaces. I later tested it on a piece of flat cardboard with no inner corrugations, that was a non-protected - non-shipping box, used for dry food storage, and it was found that the stamp worked 80% okay. The design was clearly visible and there were no issues with portions of the design missing from view. When the stamp was used on boxes meant for shipping via the postal services, it was found that the stamp, printed in hard PLA material, had no ability to get the design down into the grooves, or valleys, caused by the internal corrugations between the outer layer of the box. The purpose of the inner corrugations is meant to allow the box to withstand crush and impact forces. Sadly, this also warps the outer cover that keeps the package together, and also water resistant. The stamp simply can't reach between these micro valleys to deposit the ink. Partial prints also occurred on flat-pack paper envelopes and padded envelopes. I would encourage the people printing the design to use my newly-created dual-tone colored design in order to apple a TPU material to the bottom of the stamp. Or don't, and give the full PLA printed model a chance and see if your results differ... I'd be interested to know! I would encourage the design to make the minor recommended revisions, and I'd be more than happy to try them again! This may be the design that prompts me to get some TPU material to try out.

my local ups/fedex stores will love these
