If you can modify the placement of the seams in your slicing software, we suggest using a random distribution of seams, it’ll make it more round.ĥ0% infill, 0.2 mm layer thickness, 1 mm wall thickness, standing up and with support structure! This part has to be rather smooth as well. Putting a bit of vaseline between roller and side part can help as well. Use a file or more sandpaper to ensure a smooth movement of the roller. Also make sure that the bearings of the roller fit the bearings of the side parts. FDM printers might not be perfect at printing circles, so measuring the roller after printing and smoothing it with some sandpaper can be helpful. Keep in mind that this roller needs to be as round as possible. It’ll make the part stronger than just using higher infill percentages.ĥ0% infill, 0.2 mm layer thickness, 1 mm wall thickness and standing up! Some 3D-printers will need to use support structures for this to print successfully. Making these parts solid (100% infill) will make them very sturdy, but if you don’t have the time or material, we suggest increasing the perimeters/wall thickness of the part. If your printer is welding these parts together you might need to edit the STL file and change the tolerance of the parts.
Make sure they can easily move up and down. After these are finished you need to use a wrench to free the moving parts in which the upper roller is going to be placed later (a). We recommend printing it with at least 40% infill, 0.2 mm layer thickness, 1 mm wall thickness and flat on the ground to make it more stable against the amount of pressure that is going to be applied to the press table. This will be the most time consuming part to print. We suggest using PLA instead of ABS, because it's much more durable, easier to print and not as flexible! The press-assembly consists of 10 3D-printed parts, two M5 screws and two regular M5 hexagon nuts. Keep in mind that they are published under a Creative Commons Attribution-NonCommercial License. Hi everyone! In this blog post we’ll show you how to 3D-print your own tiny etching press! Because the press needs to be as durable as possible, there are a few things to pay attention to.Ī) 2 x side part – B) upper roller – C) lower roller – D) press table – E) roller wrench – F) lower roller pin – G) 2 x M5 screw – H) 2 x M5 hexagon nut – I) top connector – J) 2x side connector – K) printing cloth/feltsįirst you will have to download the files on Thingiverse:
