1/3/2024 0 Comments 3d clock plansLead rods are cheaper than BB's and I expect they will give a higher density. I found a local business that sells lead bars and I plan to fill a shell with 10x10mm square bars. The current design seems too bulky to me. I still have to print the weight shell. This piece allows the clock to be vertically aligned by means of two opposite bolts. I designed a U-piece that attaches to the wall and supports the bottom of the clock (picture). It's a bit difficult to make the hole in the center of the wall of spacer_4a (only 5 mm thick) to keep the bolt head right in the middle (not sticking out on either side of the spacer), so I ended up redesigning the spacer with the screw hole already prepared (picture). Instead, I made a small hole in the wall of these pieces (2 mm drill) and screwed in an M2.5 bolt which perfectly fixed the pieces to the rod. Gear4b_18 and spacer_4a must have a snug fit to the rod (epoxy and shaft collar are recommended alternatives). In Spain we use metric screws, so I choose M4 screws except for the gear7c_clicks where I used M3. I didn't use screws (I don't like them) but metal inserts and bolts. I removed it manually (X-Acto, sandpaper) from the pallet and scape but didn't do any or just a few touches on the other gears. I understood too late the advice to fix elephant's foot (I use Cura and the parameter for this fix has a name I didn't recognize). I like how I can sand it down to get a really smooth surface. If anyone were to ask me, I would recommend ABS over PLA. I printed it with enclosure (about 33 ✬) and heated bed (90 ✬). They printed perfect, only one of the pieces (gear9_inserts) had to be reprinted due to a small warp. I almost finished it (version 15 days, picture). I'll let you know how the ceramic bearings work out. In both clocks, the drive trains seem to run very well and will keep going on momentum for many seconds after the weight is removed. ![]() That clock has simply stopped for no apparent reason every 5-7 days. If these work out, I'll get a pair for my first build. ![]() I have two ceramic bearings on order, but they are on a slow boat from China (well, they will probably come by air, but I still won't see them for weeks). They seemed OK, but what else can it be? I can't even get 10 minutes of swing time. I can't seem to get good performance out of the pendulum. At the moment I am having trouble keeping it running. You might have seen that I posted a few photos of my second build of the Easy Build clock. I don't think I'll be giving you any clock design competition anytime soon, but at least I'll be learning something new. I found a copy of "The Modern Clock" on Amazon for about $17. It is worth downloading these gears and re-printing them even if you have a functional clock. The file names have a "_1" suffixe added by MyMiniFactory to indicate a revision. This change will significantly reduce the possibility of the escapement stalling and stopping the clock. Update 10-Apr-22: Refreshed gears 3 and 4 to add a slight helical angle so gear 3 pushes away from the escapement. The notes call for nut_0p25.stl and nut_0p40.stl, but the included files are knob_0p25.stl and knob_0p40.stl. Also, a small typo was identified in the assembly notes. It can be printed instead of frame_back_left.stl. Update 01-Jul-21: Added frame_back_left_hook.stl as an optional frame component with a small hook for storing the winding key behind gear 9. ![]() This design was printed on a Prusa MK3S, but will easily fit on a Prusa Mini or any machine with a print volume of at least 160x160x150mm. The list of non-printed components is half the size of my other designs.ĥ-10 lb. Building a clock that only needs to be wound once a week is still pretty impressive. I have noticed that the gears run better when printed using normal PLA, even though silk PLA can produce really nice looking gears. The longest 32 day option is a bit aggressive and the beat needs to be set accurately for it to run properly. The shorter runtimes will be more reliable and the clock should run using smaller drive weights. Different options are available with runtimes ranging from 7.8 days to 32 days. This is a great starter clock because of the simplified construction. Use the forum at to discuss clock making topics or assembly issues. Go to to download the latest assembly guide. Some of the changes that make this clock to be easy to build also made it more efficient and the runtime was able to be significantly increased. This is my easiest to build clock with a runtime of up to 32 days.
