Bag Hook

A bag hook strong enough for ordinary backpacks / rucksacks with typical loads. ~50g of PLA per hook.

Printed out of PLA with high quality and strength settings. PLA is good enough for this application. If you expect to put very heavy backpacks on them, consider printing out of ABS. If there's a risk kids will try to climb/pull on them, you may want to consider using PETG to reduce the risk of sudden snapping (PETG stretches more gradually rather than snapping like PLA or ABS; ABS has higher impact strength for sudden shocks).

⚠️ Important: Screw holes are at a 10 degree angle to improve anchoring into drywall / plasterboard. 

Please drill your holes at a similar angle for easier and strong installation. The screws will still go in if you drill perpendicular holes but it's not ideal. 

Please also be careful when screwing in (e.g. with a power tool) because the layer-lines run vertically, so vigorous screwing can crack the part. It's plenty strong enough for normal use.
