This is a front loader accessory for the "Easy to print Generic Front Loader (esc: 1:100 or HO Scale)" by "guaro3d" (Luis Corado). However, it is in N-Scale (1:160 ratio).
In order to print it for the unmodified/unscaled front loader, it needs to be scaled up by a factor of 1.6 (160%). For HO-Scale it needs to be scaled up by a factor of 1.84 (184%).
This will (most likely) NOT print on a regular FDM printer. A 0.3 mm Nozzle is necessary to print this part in N-Scale. It should print out just short of awesome on the Anycubic Photon DLP printer, though I haven't tested that yet.
I suppose 1:100 or 1:87 should be okay on any regular printer with a 0.4 mm nozzle. But beware, the parts are delicate and might break easily. This thing is purely for decoration.
The log fork and grapple are two separate parts. I carefully drilled holes into both models to insert a piece of brass wire. I initially reused the basic design of guaro3d's attachment (hence I selected that this is a remix), but had to rebuild it, as it didn't scale well after fusing both parts. I ended up doing it from scratch.
The photo below is actually a make with the earlier variant of the log fork. This thing contains the upgraded variant shown in the rendering above.

Printer used: Tevo Tornado (the printer selection is buggy and always requires to select a Nereus as soon as Tevo is selcted as a brand).
Smaller Nozzle required for N-Scale print: 0.3 mm recommended.
I used a brim (6 lines of skirt with 0 mm distance from the parts). The parts are tiny, so I positioned them in such a way, that the brim overlapped and formed a continous base-layer.
Assembly instruction notes
Refer to the documentation of the "Easy to print Generic Front Loader", as it shows where to attach the log grab.
After printing, drill out the holes with a suitable drill bit (0.6-0.8 mm should work) usinmg a hand drill (or finger drill). The wheels can be fixed to the axles using a tiny drop of thin cyano-acrylate (CA). This will work for all the joints, but be very sparse with the CA. It will seep into the cavities (capillary action) and might glue the joints together quickly.
By the way, when assembling the front loader attachments with an L-shaped piano wire and without glue, the attachments can be exchanged at any time using a set of needle nose pliers and some patience. But then, at 45 minutes printing time (including the wheel loader), its probably not worth the hassle.
