crazy story [printed a hook to hand bikes]

[threedee4me]

crazy story printed a hook to hang bikes on the garage wall. i have a flashforge finder. printed the hooks great, screwed them into a beam and hung 2 bikes. a couple of days later i find the bikes on the floor i was like what the... one of the hooks cracked off. lucky it only nicked my car. Bottom-line a few questions arise:

[1] i think there is a way to print the hook with more density and will that help? if so how?

[2] can i start to print the hook then pause and lay a piece of metal down then continue printing over the metal?

[3] other options?

[4] would the heat level in garage weaken the pla material?


thanks
